FIELD: gold traction from copper-bearing concentrates. SUBSTANCE: method provides for cyaniding, filtering, cementation and melting of cement settlings on ingot. Before filtration concentration of free cyanide in pulp is decreased to 0 - 5 mg/l and before cementation concentration of free cyanide in solution is reduced. Method allows to increase gold extraction in ingot by 1.4 times as compared with known method. EFFECT: increased gold extraction.
