摘要

A method for extracting gold from cyanidation tailings of carbonaceous sorption-active ores and beneficiation products, including filtration of the tail slurry on filter presses with the return of the filtrate to the cyanidation cycle or for neutralization, characterized in that the slurry is heated and the slurry is filtered at a temperature of 70-130 ° C and a pressure of 0.2-0.6 MPa, after filtration, the cake on the filter is washed with pre-heated circulating cyanide solutions or water at a temperature of 70-130 ° C and a pressure of 0.2-0.6 MPa, the main and washing filtrates are combined, cooled and they are demetallized by sorption or cementation methods.
