Optimization of the combined beneficiation scheme and increase in the performance of highly efficient refractory gold-bearing ores under development

Abstract

The growth in consumption and cost of precious metals is forcing gold mining companies to expand their raw material base and study and develop processes aimed at increasing the recovery of gold from ores and concentrates. The reserves of rich, easily-enriched gold-bearing mineral raw materials are practically exhausted. To maintain the volumes of extraction of precious metal, the domestic gold-extracting industry constantly involves new gold deposits in processing, resumes operation of previously abandoned and "mothballed"quarries and landfills, mines and mines, processes man-made dumps of many mining and processing plants containing a certain amount of metals (in as associated components or not completely extracted during primary processing).
