belt sintering machine, 2 * 80m3, 2X3MW blast furnace gas power

generation and auxiliary power supply system, water supply and

drainage system, environmental protection facilities and fire safety

facilities etc. are proposed. The technology system is based on the

basis of the induced technology digestion, innovation and promotion

and the combination of Indonesia actual situation. This project takes

the environment friendly enterprise construction resource conservation

as important strategic objectives, based on a high starting point, high

efficiency and high level to promote the construction of Indonesian

nickel iron alloy base, shall make the contribution for the orderly and

scientific development of Iindonesia nickel industry.

1.3 Project construction necessity

Nickel as a strategic material, known as the "industrial vitamin",

plays an important role in the development of the national economy

and national defense industry. The main application is to manufacture

of stainless steel, high nickel alloy steel and alloy structural steel, and

widely used in aircraft, radar, missiles, tanks, ships, rockets, spacecraft,

atomic reactor and other military manufacturing; in the civilian industry,

it is often applied for structure steel, acid resistant steel, heat resistant

steel which are extensively used in a variety of mechanical

manufacturing industry, petroleum; Ni and other elements such as

chromium, copper, aluminum,and cobalt can be composed of nickel

base alloy and Ni Cr base alloy. Nickel base alloy and nickel chromium

Page 7: Feasibility Study Report on 50000TPY Blast Furnace Project

Guo ke +8613299042234 [email protected]

Page 7 /Total 118page(s)

base alloy are high temperature resistant, oxidation resistant material,

used in the manufacture of jet turbine, resistance, electric heating

elements, high temperature equipment structure parts; Ni can also be

applied in ceramic parts of anti-corrosion coating; Ni Co alloy is a kind

of permanent magnetic material, which is widely used in electronic

remote control, atomic energy industry and ultrasound technology and

other fields, nickel is used as hydrogenation catalyst in the chemical

industry. In the early seventies and the late nineties of last century,

global consumption of nickel fluctuated with war and recession, but

basically increased according to the average annual growth rate of

more than 6.5%.

Nickel ore types are mainly nickel sulfide ore and nickel oxide ore

(also called laterite nickel ore), nickel sulfide ore selecting is easier

than nickel oxide ore, mining nickel sulfide ore is main exploration, but

after years of exploration, the nickel sulfide resources are drying up,

nickel smelting companies around the world turns to focus on the

mining of nickel oxide ore resources.

1.4 The feasibility and advantages of the project implementation

1.4.1 Shortage of domestic nickel resources and the rapid

development of downstream nickel pig iron / stainless steel industry

provided the control condition of the operation integration mode.

1.4.2 The integration strategy of ore origin and product method

has obvious cost advantage

Page 8: Feasibility Study Report on 50000TPY Blast Furnace Project

Guo ke +8613299042234 [email protected]

Page 8 /Total 118page(s)

Nickel pig iron is an important raw material for production of

domestic stainless steel industry, nickel pig iron market supply

accounted for nickel metal supply 50% in 2010. Although the supply

has increased, due to Chinese nickel pig iron production mainly relies

on imports of ore and then processing, the current industry average

cost of about $9 per pound is two times the average cost of production

of global nickel manufacturers of the above, located at the high-end of

the global nickel cost curve. The integration operation of ore to

production of nickel containing pig iron in Indonesia makes nickel pig

iron cash cost expected to be reduced to $4.2 per pound, 50% less

than the domestic pig iron enterprises currently cash cost. The project

has the obvious advantage of cost competition and higher profitability

than the industry average level.

1.4.3 The integration strategy of ore origin and product is in line with

the strategic development needs

Indonesia has rich laterite nickel ore resources, but mine

development and downstream smelting is still in the early stages of

development. In addition to a small number of large

international mining group in the local operation,other mines of small

scale operations are very little further to the downstream extension

for construction of sintering or smelting factory. The

Indonesian mining law promulgated in 2009, since 2014, the important

Page 9: Feasibility Study Report on 50000TPY Blast Furnace Project

Guo ke +8613299042234 [email protected]

Page 9 /Total 118page(s)

commodities (including nickel) can be exported only by local primary

processing or deep processing ( nickel content for export should be

not less than 6%) . Indonesia nickel mine owners would have the

ability of processing and smelting enterprises to form alliances in order

to solve the problem of long-term mineral sales.

1.4.4 Chinese has stable and reliable technical advantage

Since 2005, China has tried a lot of small blast furnace

smelting iron and has gained rich experience and trained a large

number of professional smelting personnel and technical management

personnel, therefore, has reliable support for the blast furnace

smelting technology investment.

1.4.5 Project risk is controllable with ample cash flow and high

investment returning

Compared with other black and non-ferrous metal mines, the scale

of Indonesian laterite nickel ore exploitation investment is relatively

small, the project development risk is controllable. The project cash

flow and debt rate are low, the anti risk ability of the integration

operation is higher.

1.5 Main design principles

According to the Indonesian national policy on economic

construction and combined with the actual situation of the project, the

following construction principles are identified:

Page 10: Feasibility Study Report on 50000TPY Blast Furnace Project

Guo ke +8613299042234 [email protected]

Page 10 /Total 118page(s)

(1) The design conforms to the Indonesian

national current technology policy and industrial policy requirements;

(2) All professional designs meet the requirements of the relevant

design specifications of Indonesia;

(3) The process technology is mature, reliable, and advanced;

(4) The engineering has been carefully designed and saved

investment to meet the process requirements;

(5) To implement "three simultaneous" protection principle, all

kinds of pollution shall be subject to the governance of post discharge

standard.

1.6. Construction conditions

1.6.1 Main raw materials supply

Laterite nickel laterite ore supply: Indonesian mines, accounting

for about 70% of overall raw materials;

Limestone: Indonesia procurement accounted for the overall raw

materials, raw materials accounted for about 3% of the total.

Coke: China import, or using the Australian coking

coal with local lignite coke production accounted for the overall 23% of

raw materials.

Fluorite: Chinese imports less than 1%.

Page 11: Feasibility Study Report on 50000TPY Blast Furnace Project

Guo ke +8613299042234 [email protected]

Page 11 /Total 118page(s)

Brown coal: Indonesia, mainly used for power generation of about

2%.

1.6.2 Power supply conditions

Because the Indonesian power shortage, therefore consider the

use of diesel generator starting, blast furnace gas with local lignite fired

for plant power use, the installation capacity of 2X3MW. Blast furnace

gas calorific values 800~900Kcal.

1.6.3 water supply conditions

The project water source of production, life and fireproof is from

self built water supply station, water from the local river purification.

Water supply can fully meet the needs of water project construction

and project operation.

1.6.4 Traffic conditions

Plant the general location, ocean transportation is convenient, in

the island's coastal location near the pier.

1.6.5 weather conditions and seismic intensity

The local temperature is higher, and the others are equal to the

temperature of Indonesia beach. The monthly mean temperature is

26.5 - 27 degrees.

Annual average temperature is not high due to the moisture

content difference throughout the year of the region dry and rainy

Guo ke +8613299042234 [email protected]

Page 13 /Total 118page(s)

main soil, the site has good stability. The site category belongs to soft

soil. Simple site hydrogeological, groundwater type is quaternary pore

phreatic, groundwater buried depth, generally 3.5 ~ 4.5m, annual

variation of 2 ~ 3.0m, the highest groundwater buried depth is 1.5m.

Atmospheric precipitation is the supply water, surface evaporation is

the main excretion way. Plant area groundwater is weak to moderate

corrosive to concrete.

1.7 Selection of process schemes

For present extraction of metal nickel of the oxidation of nickel

laterite ore, mature technique adopts hydrometallurgy, pyrometallurgy

and other special smelting method. Hydrometallurgy can be divided

into reduction roasting ammonia leaching process, high pressure acid

leaching process, atmospheric pressure leaching process, heap

leaching process. Fire metallurgy can be divided into RKEF method,

blast furnace, blast furnace smelting low ice nickel, and nickel base

direct reduction iron. The other processs of smelting method are

atmospheric leaching method, rotary hearth furnace method, method

of biological leaching, chloridizing segregation. Because of lack of

electricity, laterite itself characteristic and weak industrial base in

Indonesia near sea area, the blast furnace is more suitable for the

current development of Indonesia with mature industrial production,

the investment and economic benefit, environmental protection,

In 2009, the world has new 4 nickel mines, including Canada's 2 seats,

Chinese 1 seat, Finland 1 seat, all is sulfide nickel deposit. 4 mine reserves

totals in 54,000 tons, the amount of resources amounted to 2,907,600 tons with

the total production capacity of 56,700 tons / year. From 2009 to 2012, the

global mineral company has announced the expansion of 5 mines, which China

2 seats, Australia, South Africa and Finland all 1 seats, all is sulfide nickel

deposit. 5 mine reserves totals 865,000 tons, the amount of resources

amounted to 3,292,000 tons with the new production capacity of the total 59,500

tons / year. May foresee, in the next two years, the global nickel production

increase is a foregone conclusion.

2.2.2 Nickel alloy production

The worldwide production of nickel mainly metal nickel, nickel alloy, nickel

block and other nickel products

Nickel alloy is the product by fire process for treatment of laterite nickel ore,

100% nickel alloy is used in the production of stainless steel.

In the past few years, the world's major nickel alloy production countries

and regions are: Japan, New Caledonia, Columbia, the Republic of Dominica

and Greek. The desired nickel alloy production in Japan of nickel laterite ore are

totally dependent on imports, other countries and regions by the local mine

production.

With the Chinese stainless steel production capacity continues to expand

and rising nickel prices, in recent years the coastal area of Southeast Asia

Chinese using nickel laterite nickel alloy production enterprises has the rapidly

growed. However, with the national energy saving and emission reduction as

well as single nickel alloy products user constraints, nickel alloy production

enterprise's competition will be fierce.

2.3 Nickel consumption

Nickel consumption can be summarized as follows: stainless steel(60%),

nonferrous alloys (14%), alloy steel (9%), nickel (6%), (3%), other castings (8%).

From the consumption structure, the world nickel leading consumer market is

the metallurgical industry, accounting for more than 80% of total consumption,

stainless steel consumption accounted for above 60% of total consumption of

nickel, referring to figure 2-2. Therefore, the demand for nickel is particularly

high related with stainless steel production. According to the International Iron

and Steel Institute released data showing, global stainless steel output in 2007

Page 26: Feasibility Study Report on 50000TPY Blast Furnace Project

Guo ke +8613299042234 [email protected]

Page 26 /Total 118page(s)

compared with 5.1% growth in 2006, up to 29,800,000T. Prior to 2012, global

stainless steel output will grow at an annual rate of 6%. According to the

organisation, the yield increase parts mainly from China, China stainless steel

yield are far more than other countries. International Iron and Steel Institute

expected, Asia's stainless steel output increased by 11.8% to 16,850,000T with

the yield increased 400,000Tt in central and Eastern Europe, Western Europe,

and the Americas Africa stainless steel output will decline slightly. Global

stainless steel output in 2006 was 28,400,000T, an increase of 16.7% compared

to 2005. China now is the world's largest stainless steel consumption, in the

2008, the use of China stainless steel ratio is the sum of the past two years the

largest user American stainless steel consumption and Japan dosage.

Figure 2-2 World nickel consumption structure diagram

Compared with the electroless nickel used in production of stainless steel,

nickel alloy used for stainless steel production, due to the iron nickel alloy, and

its shape is commonly pill or flake, can improve the production efficiency of AOD

converter, so he is popular with the stainless steel production enterprises.

Since 2005, China has replaced Japan as the largest country in the nickel

consumption in the world, the other major nickel consumption states are Japan,

the United States, Germany, China Taiwan and South Korea. After a few years,

nickel consumption has been growing steadily, until the outbreak of the global

financial crisis in 2008. Affected by financial crisis, the global economic situation

is generally low, stainless steel demand led to the decrease of the nickel

consumption appeared obvious. Global nickel consumption of 1.297 million tons

in 2008, compared with1.421 million tons of 2007 decreased by 124,000 tons

with 8.8%. Global nickel consumption in 2009 is a slight rise from the previous

year, 1.306 million tons, 0.7% increase over last year. And from the point of

consumption in different countries or areas change, nickel consumption

increased in China, and many traditional nickel consumption power

consumption is decreased.

The world's major countries nickel consumption statistics are shown in table 2

-5.

From the point of world supply and demand situation, the world nickel

consumption was 1.306 million tons in 2001 between 2009 and 2009

consumption increased by 168,100 tons with annual average growth rate of

1.8%. Global nickel production 1.327 million tons in 2009-2001 and 2009

consumption increase of 169,600 tons with annual average growth rate of 1.8%.

Visible basic global nickel consumption and production growth are synchronized.

From the domestic supply and demand situation, domestic consumption of

nickel in 2009 is 456,000 tons, average annual growth rate of 29.1% from

2001 and higher than that of nickel 26.4% average annual production growth

rate, domestic demand gap of nickel increased year by year. In recent years,

with the rapid development of China's economy, the demand for stainless steel

speeding growth, are the major cause of nickel consumption is increasing.

According to the relevant institutions analysis, global stainless steel

production in 2010 reached 30.15 million tons, which is compared with 25.03

million tons last year increasing by 20.5%, the expected in 2011 will reach 33

million tons. In 2010 China's stainless steel output reached 2010 tons,

accounting for 35.8% of global output, increased 18.4% year-on-year. Stainless

steel production of other main countries and regions such as America, Europe,

Japan, China Taiwan, also appeared a large growth, increased by 37%, 23%,

28.7% and 37% year-on-year. Therefore, with the improvement of the global

economic situation, stainless steel production is in the leap. The rapid

development of the stainless steel industry promoted the increase of nickel

consumption, and the demands for nickel stainless steel field also have obvious

improvement. The field of stainless steel to nickel consumption in 2010

year-on-year growth of 10-13%, global nickel consumption will also increase to

1.46 million tons. Global nickel market balance of supply and demand is shown

in table 2-6.

At present, to year of 2012 the global mining new increase production

capacity of about 360,000 tons shall be built, and the next few years, China

stainless steel production willnot continue to maintain the high speed growth of

nearly 10 years of state. Therefore, from the perspective of supply and demand,

the next few years market supply shortage situation the probability is very small.

In 2008, world refined nickel consumption is 1,297,000T, the average

growth rate of refined nickel consumption is about 3.4%.over the past ten years.

World nickel consumption the main countries or regions are Chinese (305,000

T), Japan (185,000 T), American (121,000 T), Chinese Taiwan (69,000 T),

Germany (90,000 T) and South Korea (76,000 t). In 2008 the six countries and

areas consumption accounted for more than 65% of the entire world's

consumption. In recent years, China nickel consumption grows very raoidly,

China nickel consumption in 2008 accounts 23.5% of the world consumption,

ranked first. The main areas of the world nickel consumption has shifted from

western developed countries and regions to the emerging economies in Asia,

such as China, South Korea, Taiwan and other countries and regions China.

2.4 Nickel price

2007 is not the ordinary nickel market year, whether it is the daily price of

nickel (May 10th three month futures price of nickel reached 52,000 U. S. dollars

/ ton), or average price (36,825 U. S. dollars / ton) are a high record. In 2008

May, nickel prices plummeted, nickel prices in October fell to historic lows,

stainless steel factory mass production, nickel alloy market rapidly shrinking, a

large number of enterprises ore heat furnace shutdown, crashed in May, and in

October the two month nickel prices, caused a fatal blow to China nickel alloy

industry. The new project nickel alloy is gradually stopped or delayed operation.

In 2009, affected by the economic situation in the big environment of the

nickel, sluggish demand in the first half of the year, almost half of the nickel

production in the parking state, LME nickel prices overall trend is upward shock

trend, the global steel industry began to pick up, and laid the foundation for the

nickel price rise. End of Feburay and March after fell below 9,000 U. S. dollars /

ton, and then the price of nickel nickel began, in the repeated shocks, breaks

through 20,000 dollars / ton, although later back somewhat, but in the end back

to US $19,000 / ton high. In 2009 LME nickel three month futures price for

14,690 U.S. dollars / ton, down 36% compared to the same period, average spot

price of US $14,662 / ton, down 35% yoy.

To 2010, in the macroeconomic environment greatly improved background,

LME nickel market rose a surge high and sweep forward market bull market.

Nickel price has made 34% of the increase in the first quarter, the two quarter

Page 32: Feasibility Study Report on 50000TPY Blast Furnace Project

Guo ke +8613299042234 [email protected]

Page 32 /Total 118page(s)

was a sudden turn for the worse, to the third quarter, subject to China implement

the "energy-saving emission reduction" target and the falling US dollar impact,

nickel prices rising trend is recovered. March annual LME futures nickel price is

21,900 dollars / ton rose 49% compared with $14,690 a ton in 2009. Nearly 10

years of international nickel (LME) spot prices as refered to figure 2-3.

In 2011 the global economy is still upward, global growth in 2011 is 3.6%,

fell 1.2% than in 2010, the developed countries and emerging market countries

increased by 2.2% and 6.4% respectively, according to the relevant agencies

predicted in 2011 China GDP growth rate is 9.2%. Country people's standard of

living and sustainable growth of the world economy and China, India in the

development of increased global demand will drive the metal further increased,

the price of nickel maintain a higher level will constitute a strong support.

Figure 2-3 the London metal exchange cash price chart

The world's major producers, investment banks and consulting institutions

in each year on a two years later nickel price forecast, but because of the nickel

price effected by supply and demand, exchange rate and speculative funds and

other multiple factors, it is difficult to predict the price of nickel. From the

prediction data of each institution in history, when the nickel price smaller

Page 33: Feasibility Study Report on 50000TPY Blast Furnace Project

Guo ke +8613299042234 [email protected]

Page 33 /Total 118page(s)

fluctuations,it is at most institutions forecast range, if the nickel price fluctuates

greatly, that whll be almost beyond the forecast range of all institutions.

Nevertheless, various institutions still to predict the price of nickel using various

prediction methods.

According to the laws of economic development and historical data, nickel

prices will not long remain running at high or low, but fluctuated periodically. At

present, nickel prices are on the rise, because the next few years there will be

no shortage of market supply, nickel price few beyond the historical high prices

may. But the main international currency devaluation of the dollar in the next few

years the road will continue, and laterite nickel ore cost itself is higher than the

sulfide nickel ore, nickel prices down space is limited. After the 2014 April began

the Indonesian government for nickel ore export restrictions, China last

inventory reduction,it is expected in the next few years that the trend of rising

nickel prices will be significantly enhanced, nickel price reasonable should be in

the $17,000 / ton to 30,000 U. S. dollars / ton, up and down, many of the

industry professional institutions predicted the nickel price should be in nearly

five years over $20,000. The scheme evaluation get $19000 as an investment

appraisal price.

Nickel prices for investment project evaluation should be adopted, should in

theory be a predictor of long-term average price, this price prediction and

present current price may have a certain gap, especially the current price in the

nickel price change cycle valley value or the peak, this gap will be more obvious.

Chapter VI Lime kiln

6.1 Lime kiln process introduction

Lime kiln is the use of blast furnace gas to make limestone into lime

calcination production process between 850 ~ 1200 ℃. Lime is mainly used to

remove excess water in the wet laterite nickel ore. Lime kiln has shaft kiln, rotary

kiln, sleeve kiln, myers kiln. After comprehensive consideration of blast furnace

smelting characteristics and investment, we adopted vertical efficient active lime

kiln developed by ourselves, adopting the positive pressure operation of blast

furnace gas calcining kiln. Lime is the fusion agent of blast furnace and sintering

machine production can also be used as a strong water absorption function for

laterite nickel ore dehydration. Its main component is calcium carbonate

(CaCO3), limestone and lime (CaO), CaO as the main ingredients of lime, the

basic principle is the high temperature decomposition of calcium carbonate in

the limestone into carbon dioxide and calcium lime, reaction equation is CaCO3

= CaO + CO2-42.5 kcal. Its process is that the qualified particle size (40 ~ 80

mm) of lime stone through screening measure to the car by the hosit into the

hopper on the lime kiln, through preheating it is decomposited from 850 ℃ and

finished calcination at 1200 ℃, ,after cooling it is discharged into the chain plate,

through high temperature belt conveyor to quick lime material library, bottom

feeder feeding by lime library, then it is crushed and processed into 3 mm quick

lime powder by hammer for preparation of sintering by twisted dragon conveyor
