METHOD FOR GOLD EXTRACTION FROM CYANIC PULP

摘要

FIELD: metallurgy, mining. ^ SUBSTANCE: method for gold extraction from cyanic pulp includes gold sorption by means of pulp directing to ion-exchange resin by backflow in cascade of appliances. At that sorption is implemented at the control of concentration of gold in pulp liquid phase of each appliance. At reduction of gold concentration till 0.9 mg/l it is implemented extraction of resin from appliance and its regeneration by solution of caustic soda and/or sodium chloride brine. ^ EFFECT: increasing of resin sorptive capacity and extraction increasing of solute gold. ^ 2 cl, 2 tbl, 1 ex
