Abstract
This study focuses on investigating the technogenic wastes of the gold extraction plant at the “Auminzo-Amantoy” mine of NMMC JSC and improving the technology for gold recovery from these materials. Chemical and mineralogical analyses revealed that the samples mainly consist of quartz, feldspar, clay–mica minerals, and sulfate compounds. Experimental studies using sorption-cyanidation and flotation-roasting-sorption methods showed that the gold recovery rate reached up to 79% under optimal technological conditions. The obtained results confirm that the combined processing of technogenic wastes can ensure the economically efficient recovery of valuable metals while reducing environmental impacts and increasing production efficiency.
