| Abstract: | The new comprehensive utilization technology of copper slag by-product in zinc hydrometallurgy was investigated.The optimal leaching conditions including ratio of liquid to solid of 10∶1,leaching temperature of 80 ℃,leaching agent(sulfuric acid)concentration of 3.5 mol/L,and leaching time of 8 h.The copper concentration in lixivium reaches 30~45 g/L,and the copper leaching rate is higher than 98%.The copper concentration in stripping solution reaches 45~50 g/L after extraction,washing and three-stage cross-flow stripping of copper.The cathode copper can be produced with electrowinning process. |
