Summary: | Disclosed is a process for recovering gallium values contained in a basic aqueous solution by liquid/liquid extraction thereof. The liquid/liquid extraction process comprises contacting the basic aqueous solution with a water-immiscible, organic phase comprising a substituted hydroxyquinoline dissolved in an organic solvent therefor whereby gallium is extracted into the organic phase. Thereafter, the organic phase is separated from the basic aqueous phase and the gallium recovered from the separated organic phase. The improvement in process of the present invention comprises the organic phase further comprising dissolved therein an organic dioxime compound. |
