Modular Enrichment Plants

3. 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

4. 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%
Concentrate
World-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

5. 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.
The investor can get financing and administrative support because

6. High-profitable Business

8. DPR enrichment plants
The DPR designs modular enrichment plants and performs a complete the whole cycle of works at
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;

9. 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

10. The objects of Modular Enrichment Plants

11. DPR plant characteristics
1. High economic efficiency
2. Short-term of investment return (2
months or more)
3. Ecological safety
4. Reliable operation

12. 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.
«We put your idea into result within 4 months»

13. Equipment
• As part of the project enrichment by
gravity jigging, the complexes are
equipped with production equipment
by NPP ―Gravikon‖
(Lugansk, Ukraine).

14. 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%

15. 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.

16. Experience
