Abstract
In recent years, a new direction has appeared in metallurgical processes according to which the processing of concentrates is carried out by a combination of mechanical and metal-thermal methods of recovery. This contributes to the intensification of further redox processes and the production of fundamentally new modified products. In the case of enrichment of oxidized copper minerals, a more acceptable type of surface activation are mechanical activation processes with a combination of added reagents. It is established that sulfiding of oxidized copper minerals with elemental sulfur, silicon and sodium sulfides proceeds actively. As a result of the research, the optimal modes of sulfiding oxidized copper ores are determined. As a result of comprehensive research, a technology has been developed for processing oxidized copper minerals in a mill by sulfiding and subsequent flotation.
