METHOD OF PREPARING GALLIUM CONCENTRATE FROM ALUMINOCARBONATE DEPOSIT Russian patent published in 1995 - IPC

Abstract SU 1823980 A3

FIELD: chemical technology. SUBSTANCE: preparing gallium concentrate from aluminocarbonate deposit is carried out by step carbonization of solutions and aluminium hydroxide, gallium concentrate and hydrocarbonate solution were obtained. Carbonization is carried out for three stages: at the first stage up to attainment alkaline concentration 21-45 g/l in pulp liquid phase (as Na2Oxy) by saturation of soda-alkaline solution with aluminocarbonate deposit, and at the second and third stages with carbon dioxide. EFFECT: improved method of gallium concentrate preparing. 1 tbl
