| Abstract: |
| The zinc leached residues was leached under pressure with the objective to address the problem existing in the recovery of gallium and germanium. The effects of initial acid concentration, temperature, SO2 partial pressure, ratio of liquid to solid and stirring speed on leaching rate of gallium and germanium were studied. The results show that the total leaching rate of zinc, iron, gallium and germanium were 92.79%, 97.87%, 94.09% and 75.18% respectively after the acid leaching in high temperature. |
