FIELD: precious metal technology. SUBSTANCE: invention relates to hydrometallurgy of precious metals, in particular to recovering precious metals from cyanide solutions and/or pulps. Method comprises sorption, desorption of solutions, and electrolysis. Novelty resides in that, after desorption, solution is separated into rich and poor portions, the latter being returned to desorption stage and the former, without cooling, routed to electrolysis. EFFECT: increased concentration of precious metals in solutions before electrolysis.
