摘要：

Results are provided for a study of the substance composition of rebellious gold-copper-arsenic concentrate. The nature of gold dissemination in concentrate mineral components is demonstrated and it is established that gold is associated to a considerable extent with iron sulfides, and less with oxides. Based on results of substance analysis, comparative production schemes are proposed for extracting valuable components (Cu and Au) from Tarror deposit flotation concentrates. As a result of research, a production scheme is selected including the following operations: ultrafine grinding, autoclave oxidation, alkaline atmospheric treatment of autoclave oxidation cake followed by cyaniding.
