摘要

Alternative methods of processing the refractory gold-sulfide ores and concentrates were worked out The gold-containing refractory sulfide ores of chalcopyrite, pyrite, barite-polymetallic, quartzites, copper-zinc, antimonite were used in the research. As a result of investigation, the optimal conditions of gold leaching by means of thiourea method from the above-mentioned ores and concentrates with 85-90% gold extraction were established. Investigations were carried out on electrochemical leaching of refractory gold-containing sulfide ores and concentrates. We used the acid chloride electrolyte, which contained thiourea as a selective complex-maker for precious metals. The leaching proceeded in conditions of "soft" oxidative mode yielding up to 87% of gold without isolation of molecular chlorine avoiding environmental pollution. The new technological scheme of gold leaching satisfies modern ecological and economical requirements. The reactor designed for the electrochemical leaching of refractory ores and concentrates was tested and patented.
