Metso’s versatile new C120 jaw crusher has been engineered specifically for stationary quarrying and mining applications while keeping in mind the specific requirements of mobile and portable applications. Dale Kelly recently travelled to Mozambique with Metso to see a perfect African fit for this solution in an arduous contracting, aggregate and mining process and to find out more about Metso Minerals’ African strategy.

Sand and aggregate quarries in KwaZulu-Natal are among the best in the country and show high degrees of compliance with health and safety regulations, while simul-taneously setting high standards of care for the natural environment. One of these is AfriSam’s Newcastle operation, which for the last six years, has achieved Showplace status in Aspasa’s ISHE audit.

EDITOR’S COMMENT

As members of Aspasa are aware, the diesel rebate is still an ongoing process, and the Association’s lawyer Freek van Rooyen re-

cently attended a ‘without prejudice meeting’ in early November at the SARS offices to discuss the way forward as well as the impending High Court application.

For those that are not aware of the dispute, the amendment to Note 6, Item 670.4 of Schedule 6 of the Customs and Excise Act, 1964 (the Customs Act), confirmed that quarries qualify for the diesel refund. However, since the amendment, a number of quarries have been audited and their refund claims disallowed because the activities for which refunds were claimed did not quality as ‘own pri-mary production activities in mining’ and record-keeping was said to be non-compliant.

This stance was brought to Aspasa’s attention, and the Association corresponded immediately with SARS to clarify the activities that qualify for the diesel refund. Following an initial letter, SARS said that the blasting of rock qualifies, but not the crushing thereof. In response, it was pointed out to SARS that the definition of mineral includes rock, stone, sand, etc.

Additionally, ‘quarrying’ is listed as an ‘own primary production activity in mining’. This, read together with the fact that rock, stone, stand, etc, are different minerals, it is believed that SARS cannot apply a restricted definition of quarrying activities.

From an Aspasa point of view, the application is no longer relevant as the note was amended on 13 December 2013, allowing quarries to claim for the refunds (subject to compliance with the legislation).

At the recently-held meeting, SARS has pro-posed the following:1. SARS has refused to withdraw the letters of

demand issued, but intends to amend them in terms of Section 3(2) of the Customs Act. The Customs Act allows the Commissioner to either withdraw or amend and SARS has opted to amend.

2. Aspasa members and all other quarries affected will be given the right to make representations to any notice of amendment. (This will include all the litigation matters; matters where Section 96 notices were given; and also disputes referred to Internal Administrative Appeal).

3. Following reconsideration, SARS will either withdraw or issue an amended demand which will be the subject of all the internal dispute resolution processes.

4. That the affected members withdraw the court

application; each party to pay its own cost and allow the pending disputes to be dealt with in the manner stated above.

5. SARS to look as suspension of payment pend-ing resolution of the disputes.

6. SARS to look at Tax Clearance Certificates and it requires a list of members for which applica-tion for Tax Clearance Certificates were refused. According to SARS, the refusal of the tax certifi-cate might have nothing to do with the diesel refund disputes, and it will investigate each matter.

According to Van Rooyen, SARS has empha-sised that it is important to clarify the qualifying activities and in this regard, may even liaise with National Treasury. An amendment of Note 6 to the Customs Act is also a possibility in clarifying the issue of qualifying activities.

Aspasa is sending a letter to the National Treasury, attaching the correspondence it has had with SARS, in an attempt to get a speedy resolution to this issue.

In the light of the above, Aspasa has asked mem-bers to urgently advise on whether the proposed process is acceptable par-ticularly to the members w h o h ave b e e n f a ce d with demands, and those involved in the pending High Court application. “It is in the interest of the industry that certainty be obtained regarding the qualifying activities for which the refunds can be claimed,” Aspasa director Nico Pienaar says. “If what is proposed will achieve this, then obviously it might be in the interest of the members to agree on the way forward as proposed by SARS.”

Aspasa members, if you haven’t responded yet, please contact Nico Pienaar at Aspasa directly on tel: (011) 791 3327.

As we head at a frantic pace towards the festive season, may I take the opportunity on behalf of the Modern Quarrying team to thank our readers for their support over the last year, and to wish each and every one of you a very special holiday season. May 2015 be a year of peace, happiness, good health and prosperity for us all!

INDUSTRY REPORT

Other recently released figures from Statistics South Africa show that mining production dropped

almost 6,0% in the June quarter, com-pared with last year, and the industry shed over 4,0% of its jobs.

“Deeper mines, more challenging ore bodies and recent labour unrest have all been factors in steadily declining produc-tivity,” says Dixon, adding that the sector has been slow in finding sustainable solu-tions to these challenges.

“The sad fact is that we have been conducting our mining operations in

As the latest statistics from Productivity SA show that labour productivity in the mining sector fell almost 7,0% last year, mine management urgently needs a long-term vision for an operating environment that will improve output per worker, according to SRK Consulting chairman Roger Dixon (left).

Mining’s future lies in productivity turnaround

essentially the same way for decades, and somehow expecting our efforts to have a different and better result,” he says. “The future of mining will have to be based on more innovative technology, for instance, but our research and devel-opment initiatives remain uncoordinated and under-funded.”

South Africa this year again slipped into the World Economic Forum’s global competitiveness index, falling three places to 56th out of 144 countries.

“In a productive economy, we would expect to see certain trends such as rising

levels of labour utilised alongside wage level increases in line with inflation,” Dixon says. “Mining shows the opposite trends with employment falling and wage increases regularly outstripping the over-all consumer price index.”

Recent labour disputes on mines have led to more frequent discussions about mechanisation, with Productivity SA highlighting the long-term benefits of mechanised production in the economy. With the higher profits that mechanisa-tion and automation can produce, savings are generated that will be ploughed into new job-creating enterprises.

However, mechanising and automat-ing in conditions of high employment creates a dilemma, and Dixon emphasises the importance of steady and long-term implementation of innovation in working practices and technology.

“The logistics systems on our mines are a good example of where we could improve productivity substantially. The distances from surface to the work-ing faces of our deep-level mines have increased drastically since the 1950s and 1960s, but we have not adapted our supply chain technology sufficiently to address this. We simply lose more and more productive time as workers spend a greater portion of their day travelling to and from the stopes.”

While machines and systems are vital for better productivity, so is the health of the workers themselves. To operate at their peak, staff need to be healthy, well nourished and well rested. However, it is increasingly clear that the living environ-ment around many mines – with large numbers of workers in informal housing – is not conducive to this level of wellbeing.

“Ill health, fatigue and stress also con-tribute to accidents, which in turn, erodes the productive hours that staff spend at work; not to mention the resulting work interruptions and regulated stoppages that follow an incident,” Dixon says. “It is vital for the survival of South African mines that management grasp the pro-ductivity nettle with a strategic commit-ment to development and implement new ways of working, underpinned by research and active consultation with labour and other stakeholders.”

AROUND THE INDUSTRY

Pilot Crushtec International’s regionalisation strategy has taken a stride forward following the announcement of a joint venture with Cape Town distributor Innovexx (Pty) Ltd, to establish a distribution sales and service hub, in support of the company’s growing number of Western Province customers.

National sales manager Nicolan Govender explains that the initiative is a logical continu-ation of the company’s regionalisation strategy, which has significantly enhanced its sales and marketing footprint over the past three years. “By establishing a full-time presence both in KwaZulu-Natal and the Eastern Cape province, we have experienced significant gains in market share and our association with Innovexx repre-sents a continuation of this policy in a region that holds a great deal of potential.”

Innovexx will be marketing Pilot Crushtec International’s full range of crushing and screen-ing equipment and ancillary products, which means that local customers will have direct access to brands including Sandvik, TRIO, Edge Innovate and Pilot Modular. Innovexx is strategi-cally situated in Concorde Park within the city’s Airport City complex and features extensive office, workshop and warehouse facilities.

Director Alessandro Scherf heads up the operation and his first priority has been to underpin his service offering by retaining a

BMG’s industrial productivity exhibition held at BMG Park recently, attracted more than 2 000 visitors over the two-day event.

“The BMG expo focused on productivity and how we integrate our extensive product range and technical services into tangible operational efficiencies,” explains Dave Russell, BMG director. “Activated demonstrations took place during the expo, which practically presented techniques and product features, specifically intended to transfer knowledge and skills on reliability cen-tred maintenance.”

Highlights of the event encompassed the announcement of BMG’s new CEO Byron Nichles and the celebration of the company’s 40th anniversary milestone. Over 50 global suppli-ers – including NTN, NSK, Tsubaki, Nord, Vavel, Rexnord, Hallite, Esco, Timken, Fenner and Parker – came to South Africa to participate in the event.

comprehensive stockholding of key parts and components. “This both saves time and gives us the opportunity to provide the best possible service to our customers,” he says.

Initial response to the Innovexx presence has been positive and Scherf reports that potential buyers of new equipment are encouraged by the fact that they now have both complete prod-ucts and an after-sales service and parts facility on their doorsteps. This confidence is reflected in the recent sale of two Rubble Master RM70 GO! remote-controlled tracked impact crushers to customers who are new entrants in the city’s rapidly-expanding recycling industry. Another example is the sale of a Pilot Modular sand wash-ing plant. This product is the first of its kind to be sold to a customer in the Cape.

JSE open pit mining and materials company Afrimat, maintained steady growth for the six months to August 2014 reflecting the group’s successful diversification strategy. Revenue edged over the R1-billion mark for the first time at interims. The success-ful turnaround of group newcomer Infrasors strengthened the group’s performance.

Afrimat maintains sustainable growth The top line increased 10% to R1,03-billion from R931,9-million in August 2013. Profit after tax grew from R75,3-million to R88,8-million. Headline earnings were up 23,9%, translating into headline earnings per share of 61,1 cents compared to 49,3 cents in the comparative period. Net asset value per share was up to R5,94.

Afrimat declared an interim dividend of 13 cents/share for the period. This is higher than the 11 cents/share interim dividend last year.

CEO Andries van Heerden says he is pleased with the growth across the board given that all divi-sions contributed to results. “We have managed a pleasing recov-

ery in our traditional aggregates business as well as in Concrete Based Products. While our cash position is marginally lower than this time last year, the necessary once-off investment in equip-ment and inventory during the period will improve delivery to customers and reduce manufacturing costs in time.”

He says that continued growth in HEPS reflects the positive benefit of Afrimat’s growth through diversification strategy. “The group’s growing industrial minerals operations performed well. Our initiatives at Infrasors are well on track and we are beginning to realise the strength of its assets.”

Mining and Aggregates performed well with the clinker oper-ations excelling. Van Heerden is particularly happy with the per-formance of the entire group, including the quarries that formed the basis of the group before the diversification into industrial minerals started. “The performance in spite of difficult economic conditions in South Africa is testimony to the robustness of Afrimat’s strategy,” he explains. “Afrimat has positioned its assets strategically to be resilient in the South African market which can be very cyclical at times. As a whole, the Mining and Aggregates business unit is in a positive position with all plants fully opera-tional to meet supplier demand.”

Performance at Concrete Based Products was buoyed by favourable raw material costs, which combined with cost reduc-tion and marketing initiatives to drive an improvement in mar-gins. In the same period in the previous year the business unit had incurred excessive costs as a result of strike action. Van Heerden is pleased that this has been resolved.

“Looking ahead, despite a generally-constrained macroeco-nomic environment, the group’s markets are positive,” he says. “I am confident that Afrimat’s business development focus will continue ensuring that new opportunities are pursued early, in existing markets and high growth areas. We invest considerable time and effort in identifying high growth nodes in line with gov-ernment spending.”

Van Heerden says that Afrimat is cognisant of the risks associ-ated with each of the group’s target markets and is also pursuing further growth options outside the borders of South Africa.

The group’s intention is to capitalise on opportunities in industrial minerals through Glen Douglas, the Infrasors operations and Clinker Group.

He is also an independent non-executive director and member of the Audit Committee of Bidvest Bank Limited, has been an independent non-executive director of Hudaco Industries Limited since July 29 2013, and has also served as a director of Old Mutual Life Assurance Company (SA) Limited, from October 22, 2010 to May 2, 2013.

Lester has served Basil Read in a number of capacities with distinction for many years, and has reached retirement age. “His role in the growth and development of the business has been immense,” says Neville Nicolau, CEO. “We will miss his quiet wisdom and counsel as Basil Read enters its seventh decade, and we wish him well in the next chapter of his life.” www.basilread.co.za

Anglo American, in partnership with the Development Bank of Southern Africa (DBSA) and the Investment Climate Facility for Africa (ICF), has launched a capacity building pro-gramme at 11 municipalities across five prov-inces in South Africa. The primary objective of this programme, which represents an invest-ment of R120-million for the first three years, is to strengthen institutional capacity in the areas of personnel skills and administrative systems, in order to promote municipal sus-tainability in the long term.

The programme’s key deliverables are to develop and implement plans and proce-dures to improve municipal billing systems and controls, and reduce electricity and water distribution losses at pilot municipal sites. The programme will also focus on attracting inward investment into the 11 municipalities.

“Institutional incapacity and severe skills gaps continue to hinder the prospects of many municipalities across the country,” says Khanyisile Kweyama, executive direc-tor for Anglo American in South Africa. “As a result, these municipalities struggle to generate enough revenue to maintain basic service delivery to their local communities. “Although provision of municipal services is constitutionally the responsibility of the local authority, Anglo American’s efforts to building capacity in municipalities in and around our mining operations often extends to working in partnership with local authori-ties where necessary.

New Chryso appointments

Weir acquires TrioThe Weir Group PLC has entered into an agreement to acquire Trio Engineered Products, a Chinese-American manu-facturer of crushing and separation equipment for the mining and aggre-gates markets, for an enterprise value of US$220-million.

Trio is currently represented in South Africa by crushing and screening equipment manufacturer Pilot Crushtec International. “The current distribution agreement remains intact and it is busi-ness as usual,” says René Calitz, Strategic Marketing and Communications manager, Weir Minerals Africa.

Weir is a global market leader in the provision of pumping equipment to the

mining mill circuit, where rock is separated from ore. The acquisition of Trio will build upon Weir’s recent successful entry into the adjacent comminution segment of the mill circuit. “This agreement will allow Weir Minerals to build upon its successful com-minution strategy,” Keith Cochrane, chief executive, Weir Group, says.

“We will use our group’s unrivalled global capability to promote Trio’s range of complementary products, extending our addressable market and offering our mining customers a wider range of highly engineered equipment and services. Trio’s established manufacturing capability and its scale and presence in aggregate mar-kets also provides a further platform for growth,” Cochrane says.

In addition, Weir Minerals’ global

platform and relationships across mining markets will be utilised to accelerate Trio’s original equipment revenue growth and capture a greater proportion of the after-market opportunity from the installed base of Trio equipment. Trio has a limited service presence outside of China.

It will also allow for cross-selling of Weir’s product range in the sand and aggregates markets through Trio’s well-established sales channels in North America and China. Mike Burke, Chief Executive of Trio, says: “This agreement is strategically compelling for Trio, allowing the company to leverage Weir’s market-leading service centre network to acceler-ate growth and better serve our customers’ aftermarket needs on a truly global basis.”

New Barloworld home for Metso mobile

AROUND THE INDUSTRY

Combining high capacity, large feed opening and compact transport dimensions, the Lokotrack LT200HP complements the proven and comprehensive product line of Lokotrack LT mobile crushing plants.

Metso’s mobile crushing and screening solution’s footprint in Southern Africa has been given new traction with the launch on October 1, 2014, of a dedicated Metso mobile business unit within the Handling division of the Barloworld group.

The transfer of Barloworld’s Metso business, previously part of Bar-loworld Equipment to Barloworld Handling, has the support of Metso Minerals Southern Africa. Metso Minerals appointed Barlo-

world as sole distributor for the full range of Metso mobile crushing and screening equipment in Southern Africa ten years ago.

For Metso mobile plant customers in Southern Africa, it will be busi-ness as usual with added focus provided by a dedicated resource. The Metso mobile team remains in place headed up by new general man-ager Brandon Arnold, and will continue to provide optimised mobile crushing and screening solutions to construction, quarrying and mining customers in Southern Africa, with full aftermarket care.

Barloworld Handling is geared to help broaden Metso’s market-leading mobile footprint in Southern Africa, says Barloworld Handling SA chief executive Godfried Heydenrych. “The new business unit will benefit from synergies within the Handling division, which has an extensive sales, service and support network throughout the region. Our existing markets include those of the Metso mobile business, making this a good fit.”

Barloworld Handling has been the southern African Hyster lift truck dealer for more than 80 years and also distributes the Massey Ferguson and Challenger product ranges through its Agriculture business unit. Over the past six years, Barloworld Handling’s strong customer support infrastructure has been instrumental in establishing SEM as a leading utility wheel loader brand in the local market. “Similar synergies will ben-efit Metso,” Heydenrych says.

Focus areas will include the strengthening of service capability and parts availability throughout Southern Africa.

“Our ultimate objective is to provide more dedicated time and sup-port for the Metso product, ensuring that customers have the correct equipment, excellent parts availability and the highest levels of technical support in order to maximise their uptime and increase their production capability,” he adds. www.barloworldhandling.com

ON THE COVER

With a long history in construction in Africa, Metso has substantially in-creased its African focus, which it sees as a major growth area. “The

company’s sales, service and manufacturing net-work is dedicated to supporting the sustainable de-velopment of Africa’s industries and infrastructure,” says Eric Maricot, VP Sales & Service for Southern Africa. “In South Africa our strength is historically in the mining sector, but we are fast gaining mo-mentum in the African construction sector with our mobile and fixed plant.”

In Mozambique, for example, Metso has several mobile plants on tracks and wheels, as well as fixed plants. Maricot confirms that the modular concept is proving extremely popular as it is a simple and maintenance-friendly solution. The company recently supplied and delivered an NP 1450 impact

crusher to a major cement producer; an ideal fit for the clay composite, which when wet, can cause problems.

“I believe that the market trend is moving towards a complete solution from equipment sup-ply, erection, commissioning and maintenance, and we have come up with a unique solution for the construction market,” he says.

Today, Metso does over €300-million/year in business in Africa and the Middle East region. The group has 14 locations in South Africa with branches in Zambia (Kitwe), Zimbabwe (Bulawayo), West Africa (Ghana), Algeria (which is supported by France due to the French presence in North Africa), and Dubai in the Middle East. It is truly a global business, where, for example, an order for

equipment can and has been secured in Australia for delivery in Zambia. Two recent significant African mining contracts are for First Quantum Minerals in Zambia for two MP2500s and one MP1250, and B2Gold in Namibia for a primary crusher and grinding equipment.

According to Des Pearson, who is VP for the MPS Hub, Southern Africa, Metso builds some of the largest apron feeders in the world at its manu-facturing facility in Vereeniging. Looking at Metso as a truly global service provider, he cites an exam-ple of an apron feeder order which was secured in Australia, with Metso Southern Africa handling the engineering project management and fabrication for the end user in South America.

“Africa is a very important market for Metso,”

Maricot confirms. “Mining investment, which has been strong over the last few years, is lagging, with investment in construction on the upswing. We believe that the construction business will expand in the next five to ten years because of the infrastructure challenges in Africa. In Africa, it’s not a case of opening up a quarry and then waiting for six months to a year for the plant to arrive. This is one of the reasons why the mobile business has grown; it is easier to have mobile equipment ex-stock than it is for a fixed plant.”

The upstream dam has a double-curvature wall of some 123 m high and 505 m wide. The lower dam is 45 m high and 315 m wide.

Metso’s involvement in this project was for the erection of a complete turnkey crushing and screening installation, operating continuously for a 24-month period. The material crushed was used to manufacture concrete for the building of the dam.

Leitão says that the bottom of the dam was 100 m in thickness, requiring a stringent material specifica-tion. “Automation was another important factor, and the stockpiles had to incorporate automated truck loading.” He says plant capacity was 600 t/hour, and because of the stringent specifications, the customer required closed circuit clarifiers for water treatment of about 1 000 m3/hour. Due to the tight topography of the area, the plant was designed for assembly in a relatively small area, which after 24 months, had to

be dismantled to leave space for the dam water to cover the entire site.

Leitão, who is particularly proud of this project, says reliability was a key factor in the 24 months of continuous production. The plant included high-tech dust suppression and washing systems, as well as automated truck loading systems – all of which met European safety requirements – both mechanically and electrically. The capital invest-ment for the crushing plant was in the region of €11-million. “The customer had confidence and trust in our ability to meet their requirements, and we look at this particular project as an excellent reference as far as service, design and automation is concerned.”

Most of the disassembled plant was sent to Angola for a larger dam project being built by the same company, with the rest of the equipment being sold. The plant in Angola includes three primary crushers, six cone crushers (2 x HP500; 2 x HP400 and 2 x HP300) and four vertical shaft impact crushers (B9150), along with several screens. Leitão says production has started and after 5 000 hours of work in Portugal, the plant is working well, “and while not new, it is as good as new.”

“This is what we are able to provide and what we are now selling into Africa, albeit at this point in time, on a smaller basis,” Maricot adds. “We realise that while most of the African market is not mature enough to invest in a plant of the size used for the Sabor Dam project, mobile plant is the way to go.”

Discussing the equipment, solutions and ser-vices offering for mining and construction, he says this includes equipment, spares and wares, main-tenance services, and intelligent solutions, which are aimed at the European market. “We offer two types of solutions in construction – fixed plants and mobile plants,” Maricot says. “We work with Barloworld Equipment on the mobile plant side, and they have developed a large installed base over the last ten years. For fixed plant, we are able

to supply single pieces of equipment and a turnkey solution adapted to customer requirements.”

New productsMaricot lists Metso’s latest products which have been introduced over the last year: • C120 jaw: This is the first of a new C family.

“Crusher cavity, kinematics and operating parameters have been defined and optimised to guarantee the excellent productivity for which Metso C jaws are known and valued,” Maricot says.

• ES high-energy screens: Metso’s new screens’ two unbalanced shaft lines rotate in opposite directions to generate a high-energy ellipti-cal motion. “This deceptively simple solution is more efficient than conventional horizontal screens with linear motion, and more reliable than other elliptical motion screens. What’s more, the ES series separates materials with consistency and accuracy, even in damp and sticky conditions.”

• NP impact crusher: “This is the latest addition to a field-proven range of NP Series machines. Designed for increased safety and perfor-mance, the Nordberg NP15 is the perfect choice for secondary and tertiary applications.”

JRC ConstructionWith a diversified customer base, Metso ser-vices major players such as Rio Tinto and Billiton. Construction customers include AfriSam, Lafarge, Afrimat and Holcim as well as smaller, family-owned operations in the aggregate and civil con-struction sector. One of these is JRC Construction (JRC Construções e Obras Púiblicas Lda) in Muamba, Mozambique, which has been supplied with a turnkey modular solution from Metso. The plant which includes a Nordberg C120 primary jaw crusher and a NP1213 impact crusher, also com-prises a CVB 2661-4 four-deck vibrating screen.

“We have two main markets: the Portuguese-speaking market in Angola and Mozambique, and several important connections with Portuguese and Brazilian companies. This is where Paulo Leitão comes in,” Maricot explains.

Leitão says a lot of these contractors are mov-ing to Africa mainly to the Portuguese-speaking countries, because of the slowdown in Europe. “Many of these are Portuguese companies that have worked with Metso in Europe. “Our footprint in Mozambique is mostly in construction. We have some mobiles on tracks from South Africa and Portugal and we have a few on wheels and modu-lar plants such as the one at JRC Construction.”

Discussing the JRC plant in Mozambique, he says a rock test was carried out in June 2012, with the plant quotation following in the same month. “The order was placed on 31 December, with ex-works delivery in April the following year. The plant was delivered to site in Mozambique in early June 2013, with site preparation and civil works finalised by JRC Construction in July. Erection and installa-tion commenced on 15 July and was finally com-pleted at the end of August last year. However, due

to the late availability of electricity supply by the customers, start-up and commissioning was post-poned to mid-October, with final commissioning completed on 30 October.

“We carried out rock tests and decided on utilis-ing a particle crusher for the extremely abrasive product,” he explains. “The plant was also designed for the cone crusher but thus far, with 500 hours of work completed, there is limited wear on the particle crusher, and the customer is well pleased.”

Leitão says that Metso guaranteed its customer a production of 225 t/hour of 0,25 mm, 280 t/h of 0,40 mm and a crusher run of 0,40 mm or 0,32 mm. “After the tests were completed, the plant was able to produce 265 t/h of 0,25 mm and 335 t/h of 0,40 mm, which is a 20% improvement. What is important, however, is that blasting is efficient.” He says that JRC Construction does its own blasting.

“This customer is originally from Mozambique. He had a business in Portugal and returned to Mozambique in 1998 to start up here. JRC Construction is a family-owned business and the owner José Repolho, is the boss, the president and the technical director,” he says, adding that the general manager is Marisa Conceição, Repolho’s daughter.

Taken on a visit to the quarry site, MQ could see that blasting is very efficient. This quarry operator is an entrepreneur with a sound business vision; the plant was pumping, making short work of the extremely abrasive limestone material. Modular simplicity is key in this operation, and the plant can be moved with relative ease. Leitão says the customer preferred an impactor in place of the cone crusher, which is really proving its worth. “The impactor is relatively maintenance-friendly and can also be replaced with the cone crusher if necessary.”

On the walkabout, Metso’s Alan Fletcher, who now heads up the company’s customer and prod-uct training division (see the January 2015 edition of

Modern Quarrying), says there is a greater reduction ratio with the impactor, which acts as a secondary. “This plant is fit for purpose,” he says, sweeping up some product off the stockpile in his hands. “The material looks good and the shape is unbelievable for a -37 mm. It’s plain and simple but you get what you pay for. If you want to drive a Mercedes – this plant is it – and you have good quality, rugged and reliable machines.”

Production is key: JRC Construction’s quarry site in Mozambique.

C120 JawThe versatile new C120 jaw crusher has been engineered for stationary quarrying and mining applications, keeping in mind the specific require-ments of mobile and portable appli-cations. It has been designed as a perfect fit for challenging contracting, aggregate and mining processes.

Designed on the basis of field experience, crusher cavity, kinemat-ics and operating parameters have been optimised for the excellent pro-ductivity for which Metso C jaws are renowned.

Crusher height utilisation has been optimised to provide the steep-est possible cavity cross-section. Excellent nip angle high up in the cav-ity, together with an aggressive linear stroke at the bottom, ensure high throughput capacity and reduction.

The C120 has a range of bolt-on options, including an on-board motor base and guarding for the flywheel and drives, made from specially-developed composite materials. This makes the unit simple to install as a crusher or as a complete module in new or existing plant. The crusher

is mounted without bolts between crusher and structure using mount-ing pads, which absorb the dynamic forces and reduce the dynamic loads transmitted to the structures underneath.

Discussing safety, Maricot says the C120 is designed with safety in mind. “There are a limited number of service points which can be accessed easily and safely. Lifting tools for items such as jaw dies, cheek plates and toggle plate, are supplied with the crusher plate to guarantee safe maintenance procedures and to ensure the safety of both crusher operators and mainte-nance person-nel.”

The Metso C120 jaw crusher combines excellent productivity to give the lower cost-per-produced-ton of end product.

Nordberg NP15The new Nordberg NP15 is the result of over 60 years of impact crusher experience. The unit offers a steeper feed angle to increase material pen-etration, making the discharge curve less sensitive to blow bar wear. This new design follows the industry standard for Horizontal Shaft Impact crushers (HSIs), in secondary and ter-tiary applications.

On a single drive, the 355 kW motor increases the maximum capac-ity of the NP15 by 12% compared to the NP1315.

The IC2000 automation system ensures high NP availability at the touch of a button for better plant pro-ductivity. The system provides better control of the crusher and a com-plete view of parameters for accurate crusher monitoring. The wide choice of seven different blow bars (manga-nese, martensitic steel or chromium iron for the blow bar material selec-tion and in combination with ceramic inserts), guarantees the right tool for an application.

With a new two-part rear frame, the extra large opening of the frame provides greater access to the

breaker plates during wear part replacement.

Metso has developed a new breaker plate cassette design. This patented innovation consists of a removable assembly that allows changing the breaker plate liners in a safe condition, out of the crusher.

A: maintenance bridge; B: removable breaker plate cassette system; C: steeper feed angle (50o). The new maintenance bridge allows safe access to the rotor while changing blow bars and also safe access to the highest side liners. The patented self rotor rotation is the centralised point for setting adjustment and blow bar change.

The control room consists of a ‘baby’ Scada-controlled MCC, with the plant run by one operator in its entirety. The plant can be run on either auto-matic or manual mode and operates off a simple stop/start button. It is not interlinked or controlled by elaborate switchgear which can be inhibitive, given the dusty environment.

“We have had excellent service from Metso,” Marisa Conceição says, adding that a major ben-efit is being able to deal with Portuguese-speaking

Metso people. “The plant is perfect for our needs,” she confirms, “and Paulo is always available to assist us at short notice.”

According to Leitão, Metso has had a presence in Mozambique for some four years, and has sup-plied fixed and mobile modular plants to several customers.

What was clear to MQ is that quarry operators across the border are not governed by the strin-gent safety regulations in South Africa, and the lack of walkways on some of the plant was evident. There was also an operator walking up one of the belts – something that is strictly non-negotiable back home.

Much thought has gone into the plant design and layout for an operation of this size, which pro-duces aggregate for concrete and asphalt mixing plants, roads, the civil construction sector and landscaping market.

“We have adapted our role to meet the emerg-ing African market,” Maricot tells MQ. “We believe that the Metso modular solution comes at the right cost for the right solution, and our key priority is the African market. We offer the same high qual-ity machines as those employed in fixed plants, a tested and proven production process and opti-mised plant control for efficient plant operation. We also offer the same after sales and service con-tract as for a fixed plant, together with easily avail-able components.

“We believe our modular Nordplant concept offers major advantages for African customers. The modular standard system for construction comes with a low capex and the high efficiency and easy maintenance guarantees a low opex. We offer flex-ibility, short delivery and an excellent technical and logistical support together with optimised efficiency and return on investment.”

He cites some projects in Africa which include a modular plant in Ghana comprising a C110 jaw and two HP 300 cones, and similar projects in Cameroon and Algeria.

Aggregate material stockpiled and ready for delivery. Inset: Excellent quality stone, and according to Alan Fletcher, “an unbelievable shape for a -37 mm.”

“Our Nordplant solution combines various stan-dard modules to create a plant, which means that a semi-fixed solution on skids can be installed on a light foundation, or erected on a concrete base, for example. What is of particular importance is that we utilise our standard machines to optimise the plant. We have also worked on the steel structures and frame to speed up the manufacturing process, erection and ease of maintenance; and we have tried to standardise on all the components.”

The group has come up with an innovative manufacturing and packing process, where all components can be placed in containers that can be shipped anywhere in the world. “This reduces the time between order placement and commis-sioning,” Maricot explains, adding that with this concept significantly absorbs the cost of engineer-ing. “We have also designed walkways and stairs as well as automation and electrification in these containers. In most places in Africa, a cooling sys-tem is essential and we have integrated this into the plant design.

“Our commitment is to use the same equip-ment that we use in our aggregate plants and to ensure the same levels of quality in all our prod-ucts. Our modular concept is one that we are

AT THE QUARRY FACE

Not only has AfriSam Newcastle achieved numerous safety and health awards, but it has also been recognised for its environmental standards. According to

Aspasa’s About Face auditor Alan Cluett, this quarry is the best environmentally-compliant quarry he has ever seen.

Purchased in 1963 with the readymix operation established in 1976, the quarry, which is situated in picturesque northern KwaZulu-Natal’s Nganane, has been producing aggregate and readymix materials for decades.

Asked for the reasons behind these well-earned accolades, Meyer explains that AfriSam started out on a drive a few years ago to change behaviour rather than try to manage safety by enforcing rules and standards. “We set out on a journey of behav-iour-based safety, and the Newcastle team have taken it in their stride. I really have to give the credit to each and every employee that works for us. We have a fantastic team here, with some employees having been with us for over 40 years,” he says with pride. “We also have a very close-knit staff comple-ment as we are not a large operation, and this makes it easier to manage the whole process.

“It is all based on changing the attitude and behaviour of people, and once you have managed to do that, you have won the battle. The whole idea behind the programme is to get our people not only to look out for themselves but also to take respon-sibility for the behaviour of their colleagues as well.”

AfriSam’s Newcastle operation is classified as

Kobus Meyer (right) joined AfriSam in 2005 and after a number of promotions was appointed works manager of the AfriSam’s Newcastle Aggregate operation in 2012.

in the country and show high degrees of compliance with health and safety regulations, while simultaneously setting high standards

of care for the natural environment. One of these is AfriSam’s New-castle operation, which for the last six years, has achieved Show-

reasons behind these prestigious achievements.

a small operation, with 17 employees and seven contractors. Part of the company’s load and haul function is contracted out and AfriSam Newcastle uses cleaners on a contractual basis to keep the plant tidy.

Talking about incentivising the employees in terms of their behaviour, Meyer says one of these is a scratch-card system, in which management and middle management enter the person’s details on the card which includes various tick-boxes for behaviour initiatives. “Every month in our safety

AfriSam Newcastle sets the benchmark for excellencemeeting, these cards are dropped into a box and we have three lucky draws, for R500, R250 and R100 prizes. It is quite a motivation, especially when one has a small staff complement.”

Meyer originally started off in the steel industry as a qualified millwright. Joining AfriSam in 2005 as a millwright, he was promoted to team leader in 2007, taking up the post of superintendent in 2008. Towards the end of 2011 he was acting manager, and in 2012 was appointed works manager.

“This is a small industry, and I can honestly say

that AfriSam is a great company to work for. It really looks after its employees and there has to be a rea-son why our company has been certified by the Top Employers Institute as a top employer for the fifth consecutive year. Coming from what was a very conservative industry at that time, it was such an eye-opener to work for AfriSam. Here I believe that if you are willing to work, you will go far.”

Discussing the value of audits both from an internal and external perspective, Meyer says the internal audit is run from the regional safety office in Durban by Chris Pillay and his team, and carried out on a quarterly basis. “It is also every plant man-ager’s responsibility to do his own internal audits on a monthly basis. We go on a regular walkabout through the plant and our findings are discussed at the safety meetings and registered on our SAP system.”

Asked about the value of the Aspasa audits, he believes that if these were not carried out, “we would be out of touch with the industry. What I like about the audits are that they are based on the Mine Health and Safety Act firstly and on the

ISO systems, which keeps us in touch with what is happening in the country and the rest of the world for that matter. It is the application of best practice and the Aspasa auditors who travel throughout the country to see how best practice is applied, are always willing to share their findings with us.

“Marius van Deventer for instance, has been exposed to so many industries, and Alan Cluett is a specialist in his field,” Meyer says.

As far as the DMR is concerned, he says KZN has a very good relationship with the Department. “They know that our standards are high and we have regular inspections and visits from them. We have an open-door policy and strive for a good relationship with the Department, because unnecessary stoppages and Section 54s are very unproductive.”

Asked about illegal operators, he says thankfully in his area these are few and far between, but there is a huge operation on the N11 which takes away a fair cut of the business. The road is being currently upgraded between Ladysmith and Newcastle and the contractor has opened up what Meyer says is now starting to look like a fully-fledged quarry rather than a borrow pit. “One can understand if there are no quarries in the vicinity but in areas where the industry is well represented, it is a bitter pill to swallow.

“As long as the playing fields are level and we all play to the same rules then it is fine. The prob-lem is that with some borrow pits, the contractor’s compliance is less than what is expected of estab-lished quarries.”

AfriSam Newcastle is a dolerite quarry, with good, competent rock. All the products from G1 to G4 are crushed, together with concrete products from 37 mm down to 6,7 mm, roadstone prod-ucts from 19, 13, 9,5 mm, and 6,7 mm, two crusher sands and railway ballast.

He describes production as either feast or fam-ine, with the quarry having to work 24 hours at a

time on certain projects, while sometimes barely being able to crush for a full five-day week. “That’s the nature of the business, you have to keep your costs in check when times are down and make sure that the plant is ready for the busy times. We have had a tough few months, but the last quarter has been very good for us.”

Recent projects include the supply of G2 for base material for various roads for the Amajuba District. Meyer is also responsible for the company’s readymix plant in town, where concrete products are supplied back to the quarry plant in terms of crusher sand. “We have regular block yard custom-ers that we supply with products from 13 mm down to crusher sand. As building and civil projects come up, we produce concrete stone either directly for the customer or through our readymix plant. “

Regular product testing is carried out in the on-site laboratory and samples are also sent to Durban to independent laboratories for verification.

Moving on to the plant, Meyer says the last major upgrade was in 2006/2007, where the pri-mary plant was refurbished together with the ISP stockpile and tunnel. “Since then, we have had a few maintenance projects, but not huge upgrades. Our old-generation crushers are working well for us and we maintain these machines and keep them reliable. Nicholas Kunene, our production and maintenance team leader and his team have been doing a good job in this regard. I really believe that the old-generation machines are a lot more resl-lient than the new-generation units.”

The plant consists of a 30x42” primary jaw, a 48” Telsmith crusher, and three crushers for the tertiary – a 36” Telsmith and two 36” Nordberg crushers. There are four screens in the plant, a 16x8 on the secondary, and three smaller product screens on the tertiary plant.

The quarry utilises an excavator, three dump-ers, two front-end loaders, and a water cart for con-tinuous dust suppression.

The quarry pit itself is very old. According to records, the first blast was carried out in 1964 in the days of Hippo Quarries, which later became Anglo Alpha, Holcim and then AfriSam. “In the first 20 to 30 years, there was not much growth in terms of the quarry, and in the last 15 years the quarry has expanded exponentially,” Meyer tells MQ. “We are so proud of our quarry, especially the aesthetics. We have planted aloes and trees to make it more environmentally friendly.

“Our quarry team leader Salva Govinden, has played a major role in setting new standards with regard to rehabilitation projects in and around the quarry. He has been with the company for 42 years and his experience and dedication is invaluable.”

Blasting is carried out by a rock on ground con-tract as and when necessary.

The quarry is situated in a rural area and is sur-rounded by farms. “Three-quarters of our bound-ary is on one farm, and the other quarter is on the boundary of another farm. This farm used to be the Ngangane coal mine that supported the old Eskom power station, but that power station closed down

http://www.beinternational.co.za/


AT THE QUARRY FACE

in the early 1980s, and the property was sold off to one of the farmers. The mine was rehabilitated and there is nothing left of it.”

MQ recalls that AfriSam Newcastle was one of the first operations to erect soft berms around the quarry in terms of DMR requirements, at a consid-erable cost. The berms have to be regularly main-tained, because like any stockpile, the material migrates downwards. “The quarry has installed visual barricade poles on top of the berms to help us in this regard, but we still need to use the loader from time to time to dress them up again,” Meyer says.

Rain water is stored in the old quarry pit, which has a capacity of some 2-million litres. “Because of the scarcity and expense of water, we took the decision to pump out and utilise our rain water from the quarry pit. We have a borehole on site for potable water, but for dust suppression, etc, we use the quarry water,” Meyer says adding that the Koi fish in the pit are looking magnificent.

He says bird life around the pit is excellent, and this includes the bald ibis, which is an endan-gered species, and which is nesting in the quarry. “As Jurgens du Toit said at our last Aspasa regional meeting, the game of quarrying has changed. In the old days it used to be the game of cowboys, but those days are long gone. We are now a specialised industry.”

Looking to the future in the Newcastle/Amajuba area – which, incidentally, is the second-largest growth point in KZN after Durban – there is a lot of talk about new inland ports. Today Newcastle has the largest concentration of industies in northern KZN. “There is a lot of development underway in terms of schools and the upgrade of the Madadeni Hospital, for example, and we have a very well-run district, with a hard-working mayor.” (Newcastle’s Mayor Afzul Rehman has been crowned as the best performing mayor of a local municipality for the third consecutive year. What makes these awards even more distinctive is that they allow communi-ties to have their say, and communities through-out KZN were invited to support and vote for their municipalities in various categories. These awards were held recently at the Inkosi Albert Luthuli Convention Centre (ICC) in Durban).

“So the future in Newcastle doesn’t look bad,” Meyer says. “With regard to our sector, our big-gest competition is the slag which comes from the ArcelorMittal plant. We can’t compete with pricing because it is a by-product and there are literally tons and tons of product, a lot of which is used in construction. If it wasn’t for that, Newcastle quarry would have been quite a big operation. The only area that we can compete in is our quality, which is top notch.”

Asked about his philosophy as works manager, he says he focuses on good relationships with his

people. “My employees are well aware that when issues arise, we sort these out as quickly and ami-cably as possible, and then we get back to work. I am not one for putting things on the back burner. I believe that you should have employees who are happy in what they do, because if they are unhappy, productivity is lost.”

The standard of quarries in South Africa has been lifted considerably over the last two decades. Two decades ago, the quarry manager was a jack of all trades and a master of none. Today, he has to be familiar with stringent legal compliance and needs to be equipped with a substantial amount of skills. He has to be a specialist in environmental pro-tection and au fait with current health and safety regulations. He has to have a firm understanding of engineering principals and be able to produce sand to strict specifications. – all of which make the role of a quarry manager a very important one.

Clearly Kobus Meyer is well equipped with these skills, and the fact that the Newcastle opera-tion is among the best in the country, shows that he is a specialist in his field.

FACE TO FACE WITH ASPASA


This last quarter has been an extremely busy one for the Association not least of which was a trip to Belgium in early October at the

invitation of the European Aggregates Association (UEPG) to attend the very high-level Global Aggregates Information Network (GAIN) meeting in Brussels. Ac-companied by Gert Coffee in his capacity as chairman of Aspasa, and Afrimat CEO Andries van Heerden, the trip was a very worthwhile one.

The meeting, which was attended by key representatives from the Cement Concrete & Aggregates Australia (CCAA), Ontario Stone, Sand & Gravel Association (OSSGA), China Aggregates Association (CAA), La Federación Iberoamericona de Productores de Áridos (FIPA) and

UEPG, among others, facilitated an open exchange of ideas. The discussions revealed that the industry faces similar challenges across the globe, but with different approaches and solutions. The meeting was represented by 18 coun-tries and regions which included the UK, Germany, France, Canada, Australia, Finland, Poland, China, South America, Cyprus and South Africa. All the delegates agreed on the advantages of ongoing regular GAIN communications, and there was consensus on the desirability of hold-ing the next GAIN meeting in 2016.

Asked for the reasons behind the trip, Pienaar says that UEPG promotes the interests of the European aggre-gates industry by representing its mem-bers on economic, technical, health and safety, and environmental policy. “The

organisation proactively identifies EU initiatives and policies that are likely to impact on European aggregate produc-ers, and like ourselves, provides members with concise information through regular publications and ad-hoc updates, ensur-ing that UEPG policies are considered by EU decision makers.”

This organisation has an impressive membership from across the globe from countries and regions which include: Austria, Belgium, Bosnia, Bulgaria, Croatia, Cyprus, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Israel, Latvia, Luxembourg, Netherlands, Norway, Poland, Portugal, Republic of Serbia, Romania, Slovenia, Spain, Sweden, Switzerland, and the United Kingdom.



Aspasa works towards becoming a global entity

“We wanted to make contact with similar organisations around the world that focus on sand and aggregate quar-ries. What we discovered is that many of our problems are the same; they also look at standards and the problem of recycled aggregates, and they are also trying to reduce the heavy legislation compliance because the industry is experiencing dif-ficulties in the same way that we do, in terms of the same regulations for small and large operations.

“Discussions covered the environ-ment, water impacts, air quality, biodiver-sity, marine aggregates, and permitting. Health and safety aspects covered fatality prevention, and silica exposure, and we had input from economic affairs through to public relations and communication.”

Aspasa has extended an invitation to UEPG and GAIN to hold their next

meeting in 2016 in Cape Town, which will be hosted by Aspasa.

“The focus of Aspasa is to become part and parcel of the big world out there. What we saw in France is that our mem-ber operations are in the same league as those in that country, and in some cases even better. We might not be as mecha-nised, but we can certainly hold our heads up high,” he says.

RegcomsDiscussing the importance of the local regional meetings, he says the whole idea behind these is to share information, and to build up esprit de cour. “It is a sharing experience and one can’t run an associa-tion if you don’t go out there and share. In the past, we used to hold separate meet-ings for the IQSA, Aspasa and SARMA. We now arrange our regional meetings

around a one-day event, and make sure that our members go back with valu-able feedback on what is happening in our industry. It is also very important for the Association to keep in touch with its membership.”

The KZN meeting, which is always very well attended was held recently at AfriSam Newcastle, which Pienaar says is one of the best quarries around (see article in this month’s issue). The Western Cape regional was a good one, with pre-sentations by PPC De Hoek’s GM Johan Vorster on his operation; SARMA audi-tor Karen Stansford, who is passionate about her subject; Duduzile Kunene from the DMR, who spoke about the environ-mental changes in terms of the National Environmental Management Act (NEMA) and SARMA’s Johan van Wyk, who looked at the way forward and presented some

important resolutions decided upon by the Mancom. Feedback and input by the attendees, which included the DMR’s Principal Inspector, was excellent, some of which will be reported on in the Aspasa and SARMA newsletters.

Stephan Museler from measurement specialist company EPA Survey, who also presented his product at the KZN regcom, discussed precise quarry mea-surement, which he says is essential in determining the availability of materials, as well as stockpiles that have already been removed and stored on the prop-erty. He discussed the important of Lidar (light detection and ranging) equipment and the addition of advanced new drone aerial photography methods.

WorkshopsDuring the last year, Aspasa has held sev-eral excellent workshops, and the inten-tion is to expand on these in the New Year. Pienaar has asked that members contact him directly with any ideas for future

workshops. “We have had an environ-mental and health and safety workshop, but what we are looking at in 2015 is to expand on these, and to hold workshops on EMPs, for example. Here we will ask members to bring in their own EMPs, and we will go through these in fine detail, and assist them in improving this very important document.”

Aspasa is looking at holding work-shops on risk assessment, construction regulations, a workshop for SHE repre-sentatives and a legal liability workshop, among others. “We charge a fixed fee which includes lunch, and members are given a copy of the specific legislation discussed together with the workshop’s notes in a folder. We are also planning on inviting some officials – at no cost – to come and sit in on some of these and to share information with us.

“The IQSA/Aspasa annual conference is coming up next year and we are work-ing hard at trying to source some good speakers from the Aspasa side, such as Ken Slattery, who is the chief executive of CCAA, Australia (Cement, Concrete & Aggregates), and Andries van Heerden, to talk about some pointers in the quarry business. There will also be input from the Aspasa auditors Alan Cluett and Marius van Deventer, with feedback on their audits.

“We are also going to have awards for

the best operations on both the environ-mental and the health and safety side,” Pienaar says. “We are looking at inviting someone from Metso in France to come and speak at our conference, and we have hopes of forming a partnership for crusher training in the near future. We spent two days with Metso in France, and what we gained there is that fact that they are focusing more and more on safety in terms of their equipment.”

MHSC levyPienaar recently attended a formal com-mittee meeting to discuss the MHSC levy, and the fact that one has to pay a levy in the case of a fatality. “This is where it became interesting in that borrow pits, which had authorisation were not counted despite the fact that they were classified as mines in terms of the MPRDA.”

He says the DMR’s economics depart-ment was also asked to provide input.

“I pointed out that we, as a formal industry, are being prejudiced and dis-criminated against, as the law applies to all. The matter was taken very seriously, and the DMR’s legal representative has asked if Aspasa would assist in recording all operations in the region, to see if they are on the DMR’s system.

“The only way to do this is to get a list of the ‘legal’ operations from the DMR, and to ask our members to check who is operating in their areas and to let us know. Members must also verify that their own details are correct. When we find an operation that is not on the DMR’s data-base, I will then coordinate this with the DMR’s legal team and to members of the levy task team.

“Generally, the industry is fed up with having two sets of rules. We believe that the formal industry is being bullied, while the others are not penalised. Illegal min-ing means that there is theft against the State.”

Pienaar asks that companies look at their particular regions and send Aspasa details of non-compliance.

CEO breakfast“So there are big things ahead of us,” he says, “and we are looking at pillars for Aspasa over the next five years. This will include government interaction, intelli-gent legislation, class action against the government if they don’t want to move

on certain things, training and skills development, health and safety, best practices – and these are all items that we are going to be dis-cussing at our CEO breakfast in early December.”

Outlining the reasons for the CEO breakfast, he says “we found that with the Marikana incident, for example, industry players were not working together for the benefit of the industry, and this was disappointing from an Aspasa perspective. At this breakfast meet-ing, we will be covering health and safety and environmental issues that have been picked up by our auditors, and which need to be dis-cussed at a very high level. The fact is that should things go wrong, it is the top guys who will be imprisoned.

“We will also look at environmental issues and Gert Coffee is giv-ing feedback on what we saw in Europe in terms of UEPG and GAIN as an industry body. We want to look at how we can work together in a much more beneficial way. We want to have one set of standards; we want to discuss the image of our industry. We are going to look at training and technical issues, and to look at how we, as an industry body, can coordinate and cooperate a lot more than we are doing at present.”

He says the CEO breakfast is not about pricing, and he welcomes the Competition Commission, should they want to attend the event.

All in all an exciting year ahead for Aspasa – an organisation that has grown from strength to strength, and one that is looking to the future with vigour and commitment.

Aspasa is an agent that acts on the behalf of the industry and plays an important role in assisting its members in understanding legislation and to implement these requirements, where necessary. The Association also works closely with the DMR, Sanral and other key role players to ensure that the rules of engagement are fair and that the industry is properly governed.

“To be a member of Aspasa is a guarantee that member quarries comply with the necessary legislation,” Pienaar says. “We therefore call on those people who specify, buy or use aggregates to work with our members and to communicate with the Association in this regard.”

as a drilling and blasting specialist in the Eastern Cape and soon diversified into the mobile crushing sector with its own mobile and static crushing division. In 1993 it entered the mining services sector and diversified further into bulk mining, processing and mineral beneficiation. B&E International was acquired by the Raubex Group in 2008, completing its transfor-mation into a strongly-focused crushing, mining and mineral processing company.

On the mobile crushing and screening side of the business, the company oper-ates various crushing plants ranging in

size from about 50 t/hour to 500 t/hour, and from single-stage plants all the way up to massive five-stage crushing plants. “Our equipment fleet consists of the most modern crushers on the market, giving B&E International the capability to pro-duce a range of products from road stone to high-quality manufactured concrete sand, base course, concrete aggregates, water-bound Macadam, ballast and fil-ter media,” Janse van Rensburg says. The high-quality aggregates produced are deployed from Greenfield sites through to projects on existing commercial quarries in Sub-Saharan Africa.

to prospecting for suitable rock and the operation and subsequent rehabilitation of project-dedicated quarries,” Janse van Rensburg confirms, adding that the com-pany’s continued success in this sector is predicated on its proven ability to achieve product consistency at high volumes and in remote locations.

On the surface mining and mineral processing side of the business, the com-pany has accumulated significant Build, Operate and Transfer (BOT ) expertise ranging from in-field mineral pre-con-centration through to processing run-of-mine material for further treatment such as heap leach or heavy media separation.

“Our competitive advantage is that we have been operating plants for many years and are therefore able to design plants that are more maintenance- and user-friendly as well as being more dura-ble and having a much longer service life. In addition we are able to run this with a very low overhead as engineering is not our core business at the end of the day. Thus we have all the necessary skills com-bined with highly-competitive pricing,” Janse van Rensburg says.

In addition, B&E International has the flexibility to cater for a range of plant sizes, from a 200 t/hour plant in Queenstown to a 500 t/hour plant for the Tschudi copper mine project in Namibia for Weatherly International. “We are capable of design-ing and manufacturing plants with even greater throughputs. It all depends on what the client wants.”

The company is also looking to expand its geographical footprint, with Africa a definite focus at present.

“If we get requests from the aggre-gates industry in Africa and there is defi-nitely something we can do for them, we can size any plants according to the market demand. Obviously commercial crushing is a totally different ball game as it does not help if you are able to crush 100 000 t/month but can only sell 30 000 t. We can match the plant to what-ever the specific market need is,” Janse van Rensburg says.

B&E International’s service offering is a particular boon to mining companies facing a depressed industry in general and declining commodity prices across the board, which has placed the empha-sis on cost cutting and value addition. “At Tschudi we financed that project as

well and had the client pay us back on a per-ton toll basis. This allows the cli-ent to actually take over the operation of the plant when its cash flow and margins have achieved a satisfactory level. This exposes us to a certain amount of risk but it is something we are willing to do for reputable mining companies,” Janse van Rensburg says.

Such an arrangement works equally well for both parties, as B&E International has a guaranteed income stream while the client has peace of mind in terms of plant performance. “We are prepared to run it for you on a per ton basis which is

agreed upon from the outset. If the plant does not perform according to specifica-tion then we will tweak it.”

Janse Van Rensburg confirms that B&E International’s vast experience in the industry has allowed it to offer such value-added services to its most impor-tant clients. “Not only do we now have an established track record in this regard, but it is also starting to gain momentum. If our order book increases significantly in this regard then we will seriously look to ultimately expand our design, engineer-ing and manufacturing capability.”

PRACTICAL GUIDE FOR BLASTERS

Following on from the installation of benchmarks to the changing of benchmarks and sinking to a new

level, Terblanche says rehabilitation in-cludes face wrecking; top soiling and composting; grassing and planting; alien removal and maintaining; watering and weeding new plants; maintaining fire breaks and pathways; maintaining fences; introducing wildlife; slope stability con-trol; erosion control; and open days and communication.

Face wreckingFace wrecking is a method of blasting a face as close as possible to a natural appearance to affect a footing where vegetation can take hold. Planning and starting a face wreck must start before you reach the final mining limit to ensure that there is enough reserve left to end up with the designed slope angle. This distance will depend on the face height.

I would not recommend that you attempt to wreck a face higher than 10 m; therefore you must start planning at least 20 m before you reach the final face posi-tion. To successfully rehabilitate a mined-out face, you need to follow the sequence of tasks as set out below:• Identify the area that needs to be

face wrecked for rehabilitation and demarcate.

• Start to blast the face into a wave contour. This can be done by leaving groups of holes out of the back rows in pre-determined areas at unequal distances to leave bull noses. The last blast before the actual face wreck starts, must be a single row of holes following the bull nose and wave con-tour that was achieved with the previ-ous preparation blasts. This will give you enough blasted material in front of the face for an excavator to climb on top of the blasted material, to clear blasted rock from the topsoil landings as well as making safe going down.

• Make a simple scaled front view line sketch of where you want to blast out landings at different elevations and position along the length of the face to hold topsoil for revegetation. Use the scaled line sketch in Table 1 to determine the different hole depths at the various landings when you do the blast design.

• Do the final face wreck blast and start clearing all the landings with an exca-vator working from the top down. When loading for production from the bottom of the blast, always make sure

Table 1: Front view of vertical scaled line sketch.

that there is enough blasted material left for an excavator to climb up to reach the top of the face, in order to clear the topsoil landings and to make safe.

• You are now ready to start cascad-ing topsoil over the face and onto the topsoil landings. Tip the topsoil a distance away from the edge of the face and within reach of the excava-tor. Place the topsoil with the excava-tor, by lowering the excavator bucket with topsoil as far as possible over and down and as close as possible to the face, tipping the topsoil out very slowly.

• Do not tip the topsoil directly over the face with a hauler as it will cause the topsoil to cascade with such a speed that it will overshoot some of the landings. The landings must not be overfilled with topsoil as it will cause too steep an angle of repose for veg-etation to take hold effectively. A too-steep angle of repose will also cause erosion and is also difficult to work on.

• You are now ready to start planting indigenous grasses, trees and shrubs

In this third section of Henry Terblanche’s Practical Guide for Blasters, we look at rehabilitation, as more

often than not, the responsibility of rehabilitation is included in the duties of a blaster, particularly in smaller operations. This section is divided into two activities: rehabilitation, and monitoring/logging.

Practical guide for blasters – Part IIIBy Henry Terblanche

There are few things more dramatic than watching the ferocity of a well-controlled blast.



Table 2: Facewreck results.

and to leave something of value.Be aware that if your face wreck face is running up very close to another face above and behind you, you must tip the topsoil in position before the final face wreck blast is done. This will ensure that there is enough place left for haulers and excavators to manoeuvre in to tip topsoil behind the face wreck before the final blast is done. Once the final face wreck blast has been done, the topsoil can then be cascaded over the face manually.

New dumpsNew berms and dumps must be con-structed by tipped-in layers and must also be terraced if you want to successfully rehabilitate these. The layers must be built up in no more than 1,0 m lifts to enable the haulers to compact the layers as they run on top of them when tipping the next lift. If the layers are not compacted prop-erly, the dump will be too porous to hold enough water to sustain vegetation.

If you have clay material available, it is a good idea to install a thin layer of clay between the lifts to improve water retention in the dump. A dump for

rehabilitation should never be end-tipped as the slope angle will be too steep for veg-etation to get a foothold. Water erosion is also a problem with end-tipped dumps.

Things to consider when constructing a new dump or berm:• Will it be started on level ground or on

a slope and how steep is the slope?

• Is there water seepage or springs in the area?

• Are there natural streams nearby?• How will runoff water be controlled?• What is the natural angle of repose

of the material used to construct the dump?

• Will there be a need for retaining sys-tems to be installed?

When constructing a dump or berm:• Select the dump area and demarcate.• Remove all vegetation and topsoil

and stockpile nearby for later use.• If the dump is to be constructed on

a slope, it should be levelled as far as practically possible to prevent the dump sliding and slope failure. A footing trench can also be dug on the down slope side to anchor the toe of the dump.

• Tip one layer of material over the whole area and then flatten the mate-rial with a front end loader or exca-vator. If the dump is on a slope, you must then start building the layers up from the down slope side in level plat-forms that will become wider as you move up with the slope.

• If you have clay available, you can now install a thin layer of clay on top of this first lift.

• Tip the next layer on top of the first layer with the haulers. The haulers will compact the layer below ensuring a well-compacted dump that can hold water for rehabilitation. Depending on your required angle of repose, do

ters

tock



not tip too close to the edge of the layer below as you need to terrace the sides and leave enough space to cover the sides with topsoil. Depending on the type of material, each lift should not be higher than 1,0 m to ensure proper compaction.

• Terrace the dump all the way up, to leave you with flat platforms on which to plant indigenous grasses, trees and shrubs.

Note: The width of the terraces must be

confirmed by a suitably-qualified rock mechanic. Slope stability monitoring pegs can also be installed and surveyed for reg-ular monitoring of slope movement.

Re-vegetationTo plant trees, you need to dig a hole a square hole of at least 500 mm x 500 mm x 500 mm and fill it with good pre-composted topsoil. New trees must be watered once a week in the dry season and as required in the wet season. New

trees must be watered and weeded for at least two years to ensure their survival. Installing Jo-Jo water tanks with drip irri-gation pipes will make maintenance of the trees much easier.

The advice of a horticulturist would be a great help.

Removal of aliensAlien removal can be a very intensive and expensive operation depending on the different regions of the country. In the

Going the extra mile• Tag trees with their common and

scientific names.• Start and maintain a list of birds,

mammals, reptiles and trees.• Log trees and shrubs planted over a

specific period.• Draw up a rehab plan and display it

in your office or boardroom.• Erect a lookout platform and infor-

mation centre.• Introduce more wildlife.

• Start feeding stations to attract wildlife.

• Arrange community tours to share rehabilitation efforts.

ConclusionAny of the individual actions in this guide by itself can cause a blast to not achieve the desired fragmentation, floor condi-tions, blast vibration, estimates and cost benefit, if done incorrectly.

A poorly-designed blast can cause cracks and face damage several metres behind the last row of holes affecting the next blast. • Legal liability: The blaster’s appoint-

ment comes with legal liability and he should have a good understanding of his responsibilities.

• Basic survey: To ensure compliance with the short and medium mine plan, the blaster will need some survey knowledge up to at least N3 level. He needs to be able to: read and under-stand mine plans; plan and update short-term working mine plans; install benchmarks; survey blasts; tonnage calculations; drainage; road gradient and construction; and to install con-tours on dumps.

• Advance blasting technology: The blaster must have in-depth knowl-edge of how explosives work to help him in blast design, especially when blasting close to structures and houses.

• Communication and supervisory skills: The blaster will be expected to effectively supervise and lead a team of people.

• Computer literacy: Doing reports, developing simple spreadsheets, and logging production, is all part of a

blaster’s duties and he will need com-puter skills for this.

• Mentoring and developing: The blaster must ensure that his skills are transferred to the next generation of blasters.

Every quarry has a unique character, and this guide must be used in conjunction with local knowledge in terms of geol-ogy, closeness to the neighbours, size of equipment and rock type.

There are few things more dramatic than watching the ferocity of a well-con-trolled blast.

Additional trainingFor a blaster to become fully competent, he will need additional trainings. Safety is a major part of a blaster’s everyday duties. Training in hazard identification and risk assessments is a must. The blaster must also be able to draw up a safe work pro-cedure from the HIRA and implement it.

What it takes to become a blaster• Must like to work outdoors and have

the ability to work in all weather conditions.

• Good motor skills.• Physically strong and healthy.• Mechanical aptitude.• Ability to plan and organise.• Ability to solve problems.Remember that skill will come with long-time experience; blast results will vary with the geology of the rock; and blast results must continuously be examined and design adapted.

In the Januar y 2015 edition of MQ, Terblanche provides a quarry and plant practical audit guide, which is invaluable in ensuring continued compliance with legal regulations.

Hyundai wheel loader upgradeHigh Power Equipment Africa (HPE Africa) hosted a working demonstration recently of the new Hyundai wheel loader HL 760-9 series, which is an upgrade on the previous -7 series. This event, which was held on a compost farm just outside Bronkhorstpruit, involved a display of the Hyundai -9 series machine loading com-post and mixing raw materials. Visitors

were also given the opportunity to test and operate the machine themselves.

“These robust wheel loaders, which were launched in South Africa last year, have been designed for efficient perfor-mance in arduous working conditions in mining, construction and agriculture,” says Alex Ackron, managing director, HPE Africa (a division of the Capital Equipment Group, Invicta Holdings Limited). “These versatile machines, with an operating weight of 18 400 kg and heaped bucket capacity of 3,1 m³, are suited to the terrain and load of every specific application.”

Hyundai -9 series wheel loaders, fit-ted with fuel efficient, low noise Cummins 2 tier engines, have an in-line fuel pump that delivers more power at high injec-tion pressure, for cleaner combustion and lower emission.

The fully automatic transmission sys-tem is designed for durability, minimum power loss, low noise and improved travel speed. The new clutch control design and reduced shifting shock, ensure a smoother ride when travelling.

Hyundai has redesigned these machines with new features for improved visibility and enhanced comfort for the operator. The cab has rounded front glass and larger door glass for a better field of view and a fully automatic climate control system improves heating and cooling in the cab. Other fea-tures include a tilting and telescopic steer-ing column and an adjustable wrist rest to reduce operating stress. For improved safety, the access ladder has a 20 ° incline and large, deep tread, non-slip steps.

in Zambia, is set for full commissioning in early 2015. The crusher order, worth over €11-million was selected for Sentinel as it can process large volumes of rock as a sin-gle unit. It saves costs, as fewer crushers, related infrastructure and maintenance are needed for the same or increased ma-terial production.

Designed for secondary and tertiary crushing, the MP2500 links easily with other Metso products in creating a simpli-fied, cost-effective process flow for high production requirements. According to Kevin Graney, from Metso Wisconsin, USA, who has been heavily involved in the research and development work for what he says is “Metso’s new beast,” to duplicate the performance of two MP2500s, would require four smaller MP1250s and all asso-ciated infrastructure.

“The development of the MP2500 cone crusher resulted in innovations in the area of health and safety, many based on discussions with FQML. The most important result is based on the fact that there is less equipment installed at the mine site thus generating less need for maintenance. Serviceability and ease of maintenance was also a focus during the design.”

Since the unit is so large, Metso devel-oped a new method to remove the socket which eliminates heating of the unit in a

The world’s largest cone crusher, the MP2500, photographed at Metso’s Vanderbijlpark site.

Metso has introduced the world’s largest cone crusher,

the MP2500, in response to the mining industry’s challenge to

produce more energy- and cost-efficient equipment.

Metso cone crusher evolution confined working space. This method also eliminates process variables associ-ated with socket removal and reduces the overall stress on both the socket and main shaft. Metso has a patent pending for this new concept. The company has also refined the existing jackbolt locknut design to reduce the amount of manual work, replacing this with hydraulics to simplify the same work.

The unit has a patent-pending two-piece mainframe design, double-acting tramp cylinders with tramp return cush-ioning and a patent-pending dual oil chamber counterweight.

Metso is assisting Sentinel mine to guarantee the efficient operation of the new MP2500 by stationing full-time field service engineers on-site for one year after commissioning and by stocking critical spare parts in Metso’s distribution center in South Africa as well as on site.

Asked why the company had pro-duced this massive machine, Graney says that with ore grades declining, more mate-rial needs to be processed to meet produc-tion targets, efficiently and cost-effectively. “The MP2500 reduces the amount of equipment needed for high production, reducing maintenance substantially, and with excellent circuit flexibility.”

To date, five MP2500s have been sold, two to Zambia and three to Central America. www.metso.com

Ballito Crushers has faith in SandvikKwaZulu-Natal-based, Ballito Crushers (Pty) Ltd, is a long-time supporter of Sandvik crushing and screening equipment citing the product’s inherent quality and productivity. This loyalty has been rewarded by its recent purchase of a Sandvik QJ341 tracked jaw crusher which is exceeding expectations in terms of perfor-mance and flexibility.

Pilot Crushtec International national sales manager Nicolan Govender explains that the machine was purchased in July in order to pro-duce large volumes of 0-80 mm dolerite mate-rial for use in a major construction project. “In this particular application the QJ341, using its smallest 50 mm closed side setting, is producing material to the required specification in a single pass. This process has previously been regarded as at least a two-stage operation, necessitating the use of an additional lower capacity crusher or screen, or quite possibly both.”

The savings in operating costs has been fur-ther boosted by the QJ341’s ability to deliver in-spec material at a rate of 300 t/hour, which the customer estimates to be a 30% improvement on the output of the product’s predecessor.

Clive Damant, founder and director of Ballito Crushers, has been using Sandvik crush-ing equipment since 2006, for the simple rea-son that he regards it as a brand that produces reliable products.

“Sandvik produces very, very good equip-ment and the service in respect of parts and technical back up is first class. Our new QJ341 is performing well and appears to be an excel-lent machine,” he says. “New features include the upgraded accessible hydraulic system, the level sensor above the jaw chamber and the hydraulic lowering of the main discharge conveyor. On the other hand, I am pleased to see that Sandvik has retained the hydraulic stabilising legs which limit the rocking action of the jaw.”

The delivery of the Sandvik QJ341 follows close on the heels of Ballito Crushers’ purchase of a Sandvik UJ310 semi-mobile jaw crusher at the end of 2013 and reflects the upbeat pace of infrastructural development in the region.

The new leaders in the respective 75 and 90 t class, Caterpillar’s latest generation Cat 374F L and Cat 390F L hydraulic exca-vators build on the legendary performance of the D-Series and come to market with key enhancements in terms of safety, ultra-fast truck loading cycle times, fuel efficiency, and longer-term downstream availability. These new units replace the Cat 374D L and Cat 390D L hydraulic exca-vators launched globally in 2010 and are designed to meet diverse production tasks ranging from mining, quarrying and road construction to large-scale earthmoving projects. F Series models are being rolled out to the southern African market from the fourth quarter of 2014.

Delivering power on demand, the Cat 374F L is equipped with the Cat C15 ACERT engine, and the Cat 390F L with the Cat C18 ACERT unit. These engine models, which were also fitted on the previous D-Series machines, have been further refined by Caterpillar’s research and development team. They consume significantly less fuel thanks chiefly to two new built-in features: automatic engine speed control; and automatic engine idle shutdown.

Automatic engine speed control lowers rpm according to production demands; whilst automatic engine idle shutdown turns the engine off when it has been idling for more than a specified amount of time, which can be preset via the in-cab monitor. Operators can also switch between high power and economy mode. High power is best suited to hard digging conditions.

Net power on the Cat 374F L is 353 kW (ISO 9249) and hydraulic power 311 kW (compared to 355 and 302 kW for the Cat 374D L), whilst engine rpm (opera-tions and idle time) a re d ow n f ro m 1 800 to 1 600. This results in an a p p r o x i m a t e l y 5,0% saving in fuel consumption and a 3,0% productivity gain: an estimated 8,0% plus fuel sav-ing improvement overall.

A similar 8,0% plus fuel gain is antici-pated for the Cat 390F L. Net engine power (ISO 9249) and hydraulic power on the new model is 391 kW and 341 kW (compared to 390 and 323 kW on the Cat 390D L). Engine rpm (operations and travel) are down from 1 800 to 1 700, with an approximately 5,0% productivity improvement and a 3,0% fuel consump-tion saving.

A major contributor to these machine efficiency results is Caterpillar’s introduc-tion of the Adaptive Control System (ACS) valve, a further advance on the previ-ous generation’s Proportional Priority Pressure Compensation (PPPC) system.

The factory integrated Cat Grade Control system provides depth and slope guidance, enabling operators to cut or fill to exact target elevation, saving money on fuel and materials. Real-time bucket tip positioning through the standard cab monitor guides the operator to grade.

For added functionality, machine owners can upgrade to AccuGrade™ 3D. The key benefit of this system is that it provides 3D bucket tip position and elevation guidance, indicating precisely where to work and how much to cut or fill.

An R11-million export order for a full modular plant for the Al Rosa iron ore facility in Russia has been awarded to Johannesburg-based equipment manu-facturer Osborn.

Marketing director Martin Botha says that this order was secured by the firm’s Russian dealer, North West Leasing. The full modular plant ordered offers primary and secondary crushing and screening capabilities. It features an Osborn 3042 jaw crusher, 6 x 20 triple deck screen and an Osborn 44H Gyrasphere cone crusher. In addition to this, Osborn will supply a 5 x 14 screen to be employed at the Al Rosa plant, which is situated close to Vilyuyst in Russia’s Siberia region. The machines will be shipped from South Africa to the Siberian port of Magadan.

Osborn’s robust equipment is ideally suited for the harsh operating environ-ment in Siberia, where temperatures drop to minus 40oC. This order is particularly significant as it is expected to drive further business for Osborn in Russia’s Siberia as well as in neighbouring Mongolia.

Botha elaborates on the advantages: “Our modular plants are easy to build and are mounted on skids, so they are easier to set up. They are also easy to transport and re-erect on a new site. These plants are designed to fit into containers when they are dismantled, which makes trans-portation easier and cheaper. For cus-tomers seeking equipment that is easier to transport, Osborn modular plants offer an affordable solution that fits this bill. They are ideal for plant expansion. All that a customer needs to do is put down a concrete slab, unpack their new modu-lar plant and their expansion is done. They

In response to an increasing number of customer requests, Babcock will intro-duce a 6,0 t wheel loader with a 3,5 m3 bucket to its SDLG range early in 2015. The LG968 slots perfectly into the existing range of LG918, LG938, LG958 and LG978 wheel loaders already operating through-out southern Africa.

“A batch of the new LG968 wheel load-ers is already on order for specific custom-ers,” says SDLG general manager Grant Sheppard. “Our customer base has been very impressed with the performance of the LG958, but several customers have asked for a wheel loader slightly larger than this, but smaller than the LG978. The new LG968 has a similar drive train to these models and provides excellent accessibility for rehandling applications.

The 18,4 t LG968 is an excellent choice for re-handling or light quarry applica-tions. Its robust front and rear frame are optimised to handle the highly intense

VSD (frequency-controlled) technology forms part of Atlas Copco’s strong energy saving drive to achieve maximum energy efficiency and sustainable productivity. The company’s range of oil-injected rotary screw compressors: GA VSD (GA 5-90 kW with world class FAD (Free Air Delivery), GA 90-500 kW for larger air requirements, and the more recent highly-compact 7-37 GA VSD+ clearly reflect this drive towards achieving optimum efficiency during compressed air delivery. The highly compact oil-injected rotary screw 7-37 GA VSD+ compressor range, introduced by Atlas Copco in April 2013, serves as an excellent example where Atlas Copco evaluated every part in the compressor to ensure across-the-board optimisation.

In executing the detailed engineer-ing design for the permanent surface and underground infrastructure at De Beers’ R20-billion Venetia diamond mine underground project, WorleyParsons has harnessed a methodology to create an intelligent 3D model of the vertical shaft that incorporates the historic and techni-cal information of every component. It is believed that this is the first time this methodology is being used on a vertical shaft project from the design stage. This capability is expected to become a signif-icant market differentiator for the global WorleyParsons organisation, one of the world’s largest EPCM businesses.

“In using 3D modelling to design the vertical shaft from scratch, the cli-ent has been able to review our designs and have any changes incorporated and represented in the model well before

fabrication even commences. This has effectively shortened and de-risked the design process,” says Ryan Illingworth, WorleyParsons’ project manager on the Venetia Project. “Design traditionally begins with 2D modelling and the 3D environment is only then modelled when fabrication of the components begins. However, since the many separate 2D drawings are not linked to each other, there’s always a risk when it’s assembled/constructed that, there will be incom-patibilities. On the Venetia project, as the design process has advanced, we’ve progressively created a 3D model that presents our customer with a visual rep-resentation of the infrastructure.

“Once the mine moves into produc-tion, management will be equipped with an intelligent 3D model of the shaft that can be used for maintenance planning

and control. Because the model has a database at its core, it will also be able to integrate with other De Beers database systems.

The WorleyParsons draughting team deployed on the project spent the greater part of a year prior to commencement of the design phase developing a method to network several Autodesk software pack-ages in a complex array to allow for the creation of the intelligent 3D model.

Carefully considered environmen-tal plans can take future quarries through their useful lives to be-

come highly sought-after entertainment centers, racetracks, shopping centers or even business and residential parks. If a large-scale quarry is conceived and planned correctly it can be profitably op-erated for many years or decades with the ultimate goal of turning it into an asset for society and especially for surrounding communities.

This type of ‘second-life’ usage should be considered for all quarries and can be integrated into environmental manage-ment plans (EMPs) as part of the over-all environmental rehabilitation of the property.

This is according to environmental specialist Alan Cluett who was speaking at the KwaZulu-Natal regional meeting of the Aggregate and Sand Producer’s Association of Southern Africa (Aspasa) recently. He says that quarries in urban areas especially could be developed to become sought-after properties and that more rural quarries have the potential for other types of uses such as farming, water storage, etc.

Regions such as KZN (and other parts of the country) with beautiful landscapes

and a high per-centage of income derived as a result o f to u r i s m , c a n especially make use of exhausted quar-ries to enrich sur-rounding and even to solve problems of urbanising and industrialising popula-tions, such as landfills, etc.

Aspasa has done much to change the paradigm of quarry rehabilitation by assisting government to regulate the industry, as well as through its initiative to audit members for environmental com-pliance on an annual basis. More recently the introduction of Aspasa’s own environ-mental management system (based on ISO 14001) has helped quarries to align themselves with modern-day environ-mental management requirements.

“This shows that any quarry’s EMP need not be a hindrance, but should rather be a basis for the responsible re-usage of the land. If followed correctly it can save quarry owners a fortune and can leave the land in a state that is highly saleable,” Cluett says. “Beyond guiding quarries on land use, EMPs also serve as a record of the operation’s usage rights, responsibilities and compliance. In the event of an environmental accident these management systems can also assist quarry owners in court and show how management was conducted before the event rather than after.”

Management of a quarry needs to be realistic as an EMP is legally binding and closure plans need to be adhered to. Provided environmental stipulations are met; and the public is extensively con-sulted with prior to plans being finalised, there is no reason why quarry owners cannot and should not plan quarries to have a useful life after mining operations have ceased.

Some forward-thinking quarries over-seas and in South Africa have already adopted this approach and designed environmental management and quarry closure plans that allowed the quar-ries to be developed into various types of land uses. Examples locally include: Tyger Falls Waterfront in Western Cape, Eagle Canyon in Gauteng and The Quarry

Centre in KwaZulu-Natal.Action plans to develop quarry prop-

erties include:• Reviewing existing quarry plans and

possibly adapting them to include concurrent usage, rehabilitation and closure plans that are centered on further development of the property upon the completion of quarrying.

• Working with communities to find out what their future requirements may be and if the type of land use pro-posed is acceptable and in-line with their requirements.

• Working with local government and municipalities to get inclusion in Integrated Development Plans (IDP) and regional development plans

• Developing partnerships now with authorities and development com-panies to plan and get the buy in of potential stakeholders and financiers

• Work at changing opinions of neigh-bours, communities and authorities about operational quarries and edu-cate them on the importance of sand and stone in the development of the country and its regions. Show them how future plans for the property can benefit them.

Editor’s Note: During the last year, Aspasa has held several excellent workshops, and the intention is to expand on these in 2015. If you have suggestions for future workshops, please contact either myself or Nico Pienaar. This year’s workshop on EMPs was a great success and the idea is that in the new year, in the EMP workshop, for example, members will be asked to bring in their own EMPs to work on and to develop further.
