Development of technologies for processing man-made structures with the extraction of precious metals

Short description:

Combined technology of extraction of gold and non-ferrous metals from man-made formations which are composed as spoiled tails of ore-processing and gold extraction plants of Kazakhstan was developed. This technology uses gravity, flotation, hydrometallurgical methods of ore processing, ultra-fine reduction of man-made materials, the original methods of conditioning the pulp, new reagent regimes.

The technology allows:

• cost-effective process the current and accumulated in the dumps the tailings of processing with a high degree of gold extraction and non-ferrous metals into commercial products;
• to increase production of precious and non-ferrous metals without the cost of developing new deposits;
• to restore the favorable ecological environment in the regions of accumulation of processing plant waste.

Level of readiness:

Testing, development of process procedure.
