Modular Enrichment Plants

Technogenic fields

Activities of Mining-and-Metallurgical Industry (MMI) lead

to formation of waste – gigantic technogenic fields,

which contain a valuable concentrate:

- chrome- manganese

- nickel

- iron- copper

- coal- rare-earth metals

The highly-profitable possibilities

The natural resources are exhausted while quantity of

the technogenic fields is increasing.

Modern enrichment* complexes allow to extract a

valuable concentrate with a prime cost from $4 for ton.

For example:

With a market value of ferrochrome from $1000, the profitable of mining is 4800%

ConcentrateWorld-market value for ton

Prime cost of enrichment for

ton

Enrichment`s profitability

Coal $50 - 150 $12- 15 576%

Ferrochrome $1097 - 3600 $40 - 50 4800%

Ferromanganese $1300 - 2700 $45-55 4000%

Iron ore from $130 $4 - 6 2600%

*Ore enrichment is a set of methods of separation of metals and minerals from each other with a difference in their physical and/or chemical properties

Total investment to build the plant is about $ 2,5 million

The payback period is 2 months

Extra resource

these piles cover huge areas and cause serious ecological threat

by:

• Disengaging harmful and poisonous substances permeating

ground waters;

• Frequent occurrence of fires*.

* A single burning pile disengages an average of 10 t carbon oxide, 1.5 t sulfurous

anhydride and a considerable amount of other admixing gases.

all project implementation stages:

• Object survey: sampling, determining an enrichment technique;

• Calculation of economical efficiency;

• Providing for attraction of investments;

• Complete set of development works;

• Construction of plant;

• Personnel preparing and training;

• Logistics system establishment;

• Commissioning;

• Product distribution system establishment;

• Establishment of service and maintenance

department;

Enrichment by gravitational jigging

The available experience shows that enrichment by gravitational jigging may be efficient for the

following raw materials:

• Coal

• Coal gob piles

• Piles from metallurgical works

• Manganese ore

• Chromium ore

• Piles of ferromanganese and ferrochrome

• Vermiculite

• Placer deposits (gold, titanic ores, etc.)

• Iron ore

• Diamonds

The objects of Modular Enrichment Plants

DPR plant characteristics

1. High economic efficiency

2. Short-term of investment return (2

months or more)

3. Ecological safety

4. Reliable operation

Advantage of dealing with DPR

We undertake responsibility for complete set

of works, thus ensuring maximum efficiency at

each stage.

This significantly reduces the time of launch

production and increases profitability the

customer`s investment.

Equipment

• As part of the project enrichment by

gravity jigging, the complexes are

equipped with production equipment

by NPP “Gravikon” (Lugansk,

Ukraine).

GRAVICON Modular Complexes

• The Gravicon Modular Complexes are

designed to enrich the dumps of non-

ferrous metals, coal heaps and also small

deposits of mineral resources.

Source product output — 50, 100, 200 t/h

Extraction of source raw material concentrate

— up to 99%

Advantages of GRAVICON Complexes

• High efficiency of separation;

• May be installed on unorganized areas,

near the object;

• Complete automation of all works by

complex;

• Low energy consumption

• Low operational costs.
