B.B. Beisembayev Laboratory of Special Methods of Hydrometallurgy
The method of stadial heap leaching of gold was introduced at the Vasilkovsky mining and processing plant. With the use of the created industrial plant with a capacity of 1 million tons/year, an additional 3.5 tons of gold were produced;
For the first time, a bacterial-chemical method for the disposal of waste dumps and wastewater from cyanide and arsenic was developed and introduced.
Technology for extracting copper from copper-containing raw materials by leaching dumps;
Experimental-industrial tests of the technology of technical zirconium dioxide production from industrial products of uranium production were carried out.
Main areas of research:
Development of physical and chemical laws of chemical and biochemical leaching processes of resistant mineral and technogenic raw materials with extraction of non-ferrous, noble and rare metals;
Development of technologies for complex processing of mineral and technogenic raw materials containing non-ferrous, noble and rare metals.
Scientific and technical developments proposed for implementation:
Technology for extracting gold from gold ores and industrial raw materials;
The method of disposal of wastewater from cyanide and arsenic at the gold extraction plant JSC “Altyntau Kokshetau”;
Technology for the production of technical zirconium dioxide from industrial middling products of uranium production;
Development of technologies for heap and dump leaching of copper-containing raw materials;
development of technologies for the recovery of valuable components from uranium-containing raw materials and industrial waste.
Development of technologies for complex processing of mineral and technogenic raw materials containing non-ferrous, noble and rare metals
