FIELD: metallurgy.
SUBSTANCE: method involves crushing and depulping of the ore in solution of chemical reagents. Depulping of crushed ore is performed in solution of high-purity calcium hypochlorite with chlorhydric acid in order to obtain active chlorine, oxidise sulphide minerals by means of itself and dissolve the gold in mode of high-speed impact disintegration of reaction masses. The obtained pulp is supplied for electrochemical deposition of gold on carbon-fibre fabric HAT-100 of the cathode. After electric deposition is completed, calcination of gold-bearing fabric is performed so that god sinter is obtained.
EFFECT: easier process and higher efficiency of gold removal from sulphide ores.
