ABSTRACT OF THE DISCLOSURE The invention relates to a new method for simultaneous recovering vanadium, molybdenum and gallium from alumina factory aluminate liquor compris- ing an aqueous sodium aluminate solution. The recovering is carried out in one step by electrolyzing the aqueous sodium aluminate solution at a temperature exceeding 70°C with a direct current having a current density of from 400 to 1200 A/m2 using a low-melting liquid alloy as a cathode and agitating said alloy mechanically. The gallium is alloyed into the cathode in the course of the electrolysis. By using the new process vanadium, molybdenum and gallium can be recovered simultaneously in one step with good efficiencies without any preliminary treating of the aluminate liquor and without using any anxiliary chemicals.
