| Abstract: | The effect of acid leaching conditions on leaching rate of copper and zinc in process for production of copper and zinc sulfates from copper smelting dust was studied in this paper. The results show that leaching rate of copper and zinc is above 98% respectively, and that of iron is below 0.02% by addition of sulfuric acid in step and continuous conditions.The proposed conditions are as follows: liquid to solid ratio of 3∶1,leaching temperature of 80～90℃,time for adding sulfuric acid of 1.5h,and leaching time of 2h. |
