ABSTRACT:
The starting aluminate-alkaline solutions are subjected to two-stage carbonization with stirring and the production of hydrate of aluminum oxide, a gallium-containing precipitate, and solutions containing caustic and bicarbonate alkali, thereafter the produced gallium-containing precipitate is mixed with a solution containing caustic alkali to achieve a content of gallium in the solution of 0.05 to 1 g/l, the precipitate thus formed is separated and the solution enriched with gallium is mixed with a solution containing bicarbonate alkali, the produced mixture is evaporated to separate compounds of alkali metals, and the evaporated solution is carbonized to produce a solution containing alkali metal salts, and a gallium concentrate from which gallium is produced by transforming it into alkaline solution and subsequently reducing electrochemically.
The proposed method makes it possible to extract gallium at a comparatively low cost from solutions in the processing, for example, of nephelines containing it in amounts which do not exceed 0.02 to 0.03 g/l. Owing to the proposed method it has become possible in the processes of concentration of gallium to produce a number of valuable components such as alkali metal salts contained in the starting ore.
