FIELD: chemical technology of noble metals. SUBSTANCE: gold extraction from pulp is carried out by gold sorption with activated carbon. Then autoclave gold desorption from saturated coal, gold sorption from eluate, electrolytical gold isolation from concentrated eluates and coal regeneration with its recovery to process were carried out. Gold sorption from eluate is carried out on the fresh sorbent, and after extraction and desorption of gold this sorbent is fed for gold sorption from the parent pulp. Method is used for gold extraction from cyanide solutions and pulp by coal-sorption technology. EFFECT: increased gold concentration in solutions to be feed for electrolysis.
