MIXTURE FOR PRODUCTION OF GALLIUM Russian patent published in 2005 - IPC

FIELD: hydrochemistry of aluminum and a gallium.

SUBSTANCE: the invention is pertaining to the field of hydrochemistry of aluminum and a gallium and may be used for production of gallium. The technical result is decreased consumption of expensive nepheline in the mixture, increased production of gallium out of the mixture leading to an increase of an economic efficiency of gallium production and also an ecological cost-effective utilization of a slime of production of aluminum by electrolysis, composition of which consists of bensapyrene - a substance of the 1-st class of danger with a concentration in the slime of 160 mg/kg at MPCop xone = 0.00015 mg/m³. It is achieved by the fact, that the mixture material for production of gallium and containing nepheline, limestone, white slime, soda solution and water is in addition introduced with a slime of production of aluminum by electrolysis with the content of fluorine - 1.0 1.5 %, and the components are taken in following mass %: Nepheline - 25.0-25.8; limestone - 42.6-43.9; White slime - 2.8-2.9; Soda solution - 9.3-9.6; Slime of aluminum productions by electrolysis with the content of fluorine of 1.0 - 1.5% of 2. 0-5.0; Water - the rest.

EFFECT: the invention ensures decreased consumption of expensive nepheline in the mixture, increased economic efficiency of gallium production, ecological cost-effective utilization of a slime of production of aluminum by electrolysis.
