| Abstract: |
| Sulfuric acid pressure-oxidation leaching process from tin dust with indium was studied. Effects of various factors on leaching had been investigated. The results show that leaching rate of indium can reach 93. 66% under the conditions including ratio of liquid to solid of 4∶1, H2SO4 initial concentration of 150 g/L, leaching temperature of 150 ℃, oxygen partial pressure of 0.7 MPa, and leaching time of 150 min. |
