Abstract
The authors present the data of the substance analysis of gold-copper-arsenic flotation concentrate. Gold and copper recovery by autoclave leaching of the concentrate has been studied. It is found that maximum gold and copper recovery under optimum conditions reaches 96 and 92%, respectively. The profitability of the proposed process flowsheet is proved by the technical-and-economical calculations.
