METHOD FOR EXTRACTION OF GALLIUM OF ANODE PRECIPITATE DURING PRODUCTION OF ALUMINIUM

摘要

FIELD: extraction of gallium. SUBSTANCE: anode precipitate is extracted with alkali solution at 100 C and pressure 1.5-4.5 atm, rate of air supply being 240-280 l/h. The process is followed by isolation of gallium of thus obtained solution. EFFECT: improves efficiency of the method.
