FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy of noble metals and is used for extraction of gold from copper-containing sulphide raw material by cyanidation while stirring. In leaching reagent (NaCN or other cyanide) is fed into head units of cyanidation, then conditioning is carried out by pulp agitation for 4–72 hours without supply of reagents with subsequent scalding of liquid phase of pulp.
EFFECT: considerable increase of weight ratio of gold in saturated sorbents, productive cement and cathode sediments, and also reduction of consumption of reagents for neutralization of cyanide wastes.
