| Abstract: |
| Germanium and indium are selective recovered from dezincification oxidized hard zinc slag with oxygen pressure leaching process. The dissolving performances of Ge, In, Cu, Sn, Sb were investigated. The results show that the dissolution rates of Ge, In and Zn from the hard zinc slag are up to 95%, 91% and 98% respectively, and most of Pb, Si, Sn and Sb stay in the trail slag. |
