FIELD: metallurgy.
SUBSTANCE: method of gold extraction from mercury-containing cyanic solutions consists in sorption by ion-exchange resin of AM-2B mark. Then mercury de-sorption is carried out from saturated ion-exchange resin at a temperature 40-50°C and for 6 hours and aurum de-sorption. Note that mercury de-sorption is done by solution containing sulfuric acid 30-50 g/l with the presence of hydrogen peroxide 5-10 g/l.
EFFECT: reduction of mercury content in saturated gold-containing ion-exchange resin till safe concentration or complete elimination of mercury penetration into finished products.
