| Abstract: | Recovering germanium by liquid-liquid extraction from zinc leaching solution is reported. The production capacity is 70m~3/d feed solution bearing 40~50mg/L Ge in a commercial plant. In practice, the extracting and stripping efficiencies are 95%~98%, respectively, through three-stage extraction and one-stage strip. The crude GeO_2 product contains 30% ~ 40% Ge. The extractant and stripping solution can be recycled. |
