<p>PROBLEM TO BE SOLVED: To efficiently recover refined gallium from a raw gallium material contg. impurities by electrolysis. SOLUTION: A liq. raw gallium material 3 is used as an anode, and refined gallium is deposited on a cathode in an electrolytic solution 1 to electrolytically refine gallium. In this case, the scum formed on the anode surface is discharged outside an electrolytic cell 2, the liq. raw gallium material as the anode is replenished until the electrolysis is finished, and further the gallium concn. in the electrolytic solution is kept in a specified range during the electrolysis.</p> |
