Abstract: The present invention provides for the recovery of gallium from aluminum smelting dust. Aluminum smelting dust is leached with mineral acid, such as sulfuric acid, hydrochloric acid, or nitric acid. Gallium is extracted from the obtained leach liquor with an organic solution containing a liquid cation exchange agent. The resulting loaded organic solution is treated with mineral acid in aqueous solution, either after or before scrubbing with a higher concentration of acid in aqueous solution, to strip gallium. Gallium is extracted from this solution with another organic solution containing an ion-pair extracting type extracting agent. Finally, purified gallium is recovered by stripping the latter loaded organic solution with water or dilute acid in aqueous solution.
