FIELD: processing gold-bearing materials; extraction of gold from coal and brown coal.
SUBSTANCE: proposed method consists in roasting gold-bearing material and entrapping sublimates. To this end, sublimates in form of flue gases are passed through air tube of floatation machine and floatation chamber is filled with aqueous solution containing collecting and foaming reagents, thus obtaining foam product at high concentration of gold which is suitable for further industrial processing.
EFFECT: high concentration of gold in final products.
