PROCEDURE FOR PRODUCTION OF ALUMINIUM BY ELECTROLYSIS OF MELT Russian patent published in 2011 - IPC C25C3/06 C25C3/18

Abstract RU 2415973 C2

FIELD: metallurgy.

SUBSTANCE: procedure consists in electrolysis of melt KF-NaF-AlF₃ with additives Al₂O₃ at temperature of electrolyte 700-900°C and at maintaining cryolite ratio (KF+NaF)/AlF₃ from 1.1 to 1.9. Electrolysis is carried out at anode density of current not more, than 1.0 A/cm² and cathode density of current not over 0.9 A/cm².

EFFECT: raised efficiency at simultaneous reduction of specific consumption of electric power and reduced cost of known procedure of aluminium electrolytic production; low rate of corrosion of electrode materials.
