FIELD: metallurgy.
SUBSTANCE: treatment method of gold-copper ores includes heap leaching of gold by cyanic solution with usage of spillage solution by passing of solution through ore pile. Then it is implemented gold sorption from productive solution by active carbon, desorption of gold from saturated carbon and electrolysis of eluates. Additionally it is implemented supporting of spillage solution by cyanide after passing of solution through ore pile before sorption.
EFFECT: quality improvement of cathode residues ensured by reduction of copper sorption by active carbon.
