FIELD: metallurgy.
SUBSTANCE: method relates to metallurgy of noble metals and is used for extraction of gold from milled mineral raw material by cyanidation while stirring. Leaching maintains concentration of free cyanide 3–1000 mg/l. NaCN reagent is fed into different spatial zones of the cyanated pulp in the form of a diluted solution with concentration of 0.5–50 g/l.
EFFECT: when using the method, consumption of cyanide and reagents for decontamination of tailings is substantially reduced.
