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 containing of sorption tower. At that sorption is implemented at the control of concentration of thiocyanate and cyanide in pulp liquid phase of each appliance. At achieving of thiocyanate and cyanide accumulated concentration more than 0.5 g/l into pulp it is introduced oxidant in number, which is necessary for receiving of gold concentration in liquid phase of pulp 0.05-008 mg/l.
EFFECT: oxidation and decomposition of thiocyanate and cyanide in liquid phase, encouraging increasing of gold extraction.
