摘要

FIELD: metallurgy.
SUBSTANCE: method can be used in processing of raw materials of noble metals, in particular, in cyanic leaching of gold and silver from ores and concentrates. The feedstock is treated with a leaching solution containing a cyanide and an oxidizer, which is replaced by oxygen substitutes, for example, hydrogen peroxide. The oxidizer is added in amount sufficient for the oxidation-reduction potential of the leaching solution (-0.3)÷(-0.5) V. The concentration of cyanide in the leaching solution is 1-10 g/l. The leaching is carried out at a temperature of 40-60°C.
EFFECT: as a result, the rate of metal dissolution increases by 2-3 times in comparison with the traditional modes.
