| 摘要 |
The invention relates to the method for extraction of metal gallium from aluminate solution, which comprises the electrodialysis stage, where solution for recapture, which contains captured gallium, is subjected to electrodialysis for reducing of gallium and extraction of acid, stage of removal of iron impurities, ultrafiltration stage, where obtained gallium solution will be neutralized, and obtained suspension of gallium hydroxide is subjected to ultrafiltration, stage of repeated dissolution, where concentrated suspension of gallium hydroxide is dissolved in alkaline solution, and electrolysis stage where alkaline electrolytic gallium solution obtained at the stage of re-dissolution, is subjected to electrolysis for extraction of metal gallium. |
