  • Patent number: 4256709
    Abstract: An improved method for recovering aluminum values from alkaline aluminosilicate raw material by sintering a comminuted aqueous mixture of the alkaline aluminosilicate material, limestone and soda solution wherein the alumino-silicate material is first comminuted with the soda solution to form a mixture with a fraction of particles larger than 0.08 mm greater than 20 percent by weight, mixing limestone with the mixture and comminuting until the fraction of particles larger than 0.08 mm is between 2 and 15 percent by weight.
    Type: Grant

  • Patent number: 4135917
    Abstract: 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 is treated with a liquid alloy of gallium containing an element possessing an oxidizing potential exceeding that of gallium to give a concentrate containing more than 90% of gallium by mass, wherafter gallium of a higher purity grade is recovered from the resulting concentrate by the electrochemical method.
