Laboratory of pyrometallurgy of heavy nonferrous metals
Together with VNIItsvetmet, KIVCET method of smelting copper-zinc concentrates and middlings was developed and applied/ implemented at the Irtysh Polymetallic Factory;
Together with the Moscow Institute of Steel and Alloys, the technology of smelting in a liquid bath was introduced at the Balkhash smelting factory.
A technology for converting copper mattes using liquid waste slag as a flux was developed and implemented at the Zhezkazgan smelting factory.
A technology has been developed for the reducing pyrometallurgical selection (RPS-process) for the processing of refractory gold ledge ores with the transfer of gold to matte.
The theory of the fluxing properties of silicate ores and slags of copper smelting production has been developed.
The work was done to improve the quality of rough and anodic copper at copper plants in Kazakhstan (Zhezkazgan, Balkhash, Ust-Kamenogorsk).
