A full range of studies on the processing of refractory pyrite-arsenopyrite gold-bearing concentrate and the development of design regulations for MMC Kazakhaltyn JSC

Studies were carried out on the extraction of gold from the ore enrichment products of the "Bestobe" deposit: from a gravity concentrate using intensive cyanidation, from refractory pyrite-arsenopyrite flotation concentrate using various methods of preparing raw materials for cyanidation: roasting, biooxidation, autoclave oxidation, atmospheric high-temperature oxidative leaching.
A technology has been developed to achieve high gold recovery from refractory materials.
Process regulations have been developed for the design of a hydrometallurgical department as part of a gold recovery plant for processing gold-bearing ores of the Bestobe deposit to produce metal in the Dore alloy.
