RECOVERY OF GALLIUM FROM GALLIUM CONTAINING BASIC SOLUTION |
摘要 |
<p>Process for the recovery of gallium from a basic solution such as the Bayer lye. <??>This process consists in extracting the gallium present in Bayer lye into a water-immiscible solvent and in then reextracting the gallium with a strong base solution. <??>In a second cycle the gallium present in the strong base solution is reextracted with a water-immiscible solvent and then recovered with an aqueous solution which is either acidic or basic, to produce a gallium solution which can be subjected directly to an electrolysis with a view to the production of gallium metal. </p> |
