PROCESS FOR RECOVERING GALLIUM FROM ALUMINATE-ALKALI SOLUTIONS RESULTING FROM TREATMENT OF ALUMINIUM-CONTAINING ORES

PROCESS FOR RECOVERING GALLIUM FROM ALUMINATE-ALKALI SOLUTIONS RESULTING FROM TREATMENT OF ALUMINIUM-CONTAINING ORES

A process for recovering gallium from alkali aluminate solutions which consists in that the starting alkali aluminate solution is neutralized to a concentration of the caustic alkali of from 0.1 to 10 g/l, whereafter the neutralized liquor is evaporated to a concentration of the caustic alkali there...

Zusammenfassung:A process for recovering gallium from alkali aluminate solutions which consists in that the starting alkali aluminate solution is neutralized to a concentration of the caustic alkali of from 0.1 to 10 g/l, whereafter the neutralized liquor is evaporated to a concentration of the caustic alkali therein of from 30 to 150 g/l. Then the evaporated solution is corrected to obtain the ratio between the alkali metal oxide and alumina of above 2.0. The corrected solution i
