METHOD OF PREPARING GRANULAR BLEND FOR INTRODUCING ALUMINIUM ELECTROLYZERS INTO ELECTROLYTE Russian patent published in 1999 - IPC

Abstract RU 2135413 C1

FIELD: chemical industry, more particularly preparation of granular blend. SUBSTANCE: fluorine salts are mixed, mixture is ground to fraction size of not greater than 8 mcm in amount at least 10%, calcined soda is added at sodium to aluminium weight ratio in original mixture of not more than 2.01, moistened, granulated and dried. Fluorine salts include aluminium fluoride or industrial cryolite. EFFECT: reduced losses of granular salts during electrolysis of aluminium. 4 cl, 4 ex, 1 tbl
