| 摘要 |
The present invention relates to the recovery of tin from a waste metal containing tin. A negative electrode and a positive electrode are installed in an alkaline solution, and electrolytic separation is performed, while using the waste metal containing tin as the positive electrode. The tin leached from the positive electrode is precipitated at the negative electrode. The temperature of the alkaline solution is kept between 60-90°C when the electrolytic separation is performed. |
