FIELD: metallurgy.
SUBSTANCE: extraction method of gold from tails of cyanidation of carbonic sorption-active ores and washed products includes filtration of pulp from tails on filter press with filtrate return to cyanidation circuit or to neutralisation. Before filtration pulp is heated and filtered at temperature of 70-130°C and pressure of 0.2-0.6 MPa. After filtration cake on filter is washed with preheated cycling cyanide solutions or water at temperature of 70-130°C and pressure of 0.2-0.6 MPa. Primary and washing filtrates are combined, cooled, and gold is extracted by sorption or carbonisation.
EFFECT: additional extraction of gold from tails of cyanidation of carbonic sorption-active ores and washed products.
