FIELD: metallurgy.
SUBSTANCE: invention relates to hydrometallurgical processing of gold-containing refractory ore and techno genic mineral raw material and is intended for extracting gold from them. Method consists in that stack of thrust ore simultaneously or in form of mixture is sprinkled with solution containing complexing agent for gold, and solution subjected to treatment in photo electrochemical reactor. Obtained productive solutions taken for sorption, part of parent gold-stripped solutions is reactivated by electrolysis, fortified complexing agent, pH is conditioned and supplied for irrigation stack in parallel or in form of mixture with solution subjected to treatment in photo electrochemical reactor.
EFFECT: technical result is high efficiency of procedure due to reduced consumption of complexing agent and alkalis and increase of extraction of disperse and encapsulated gold.
