| Abstract: | The roasting – water leaching process route was adopted to deal with the complex arsenic and copper- containing raw material. By this way,arsenic and copper was separated. The test results show that the roasting temperature is 550℃,the alkali coefficient is 1. 5,the roasting time is 1. 0h,the liquid- solid ratio of roasting slag water is 5 ∶ 1,leaching temperature is 60- 65℃,the leaching time is 1. 0h. Under this condition,about 99% of arsenic can be separated from the copper raw material,water leaching residue containing 76% of copper,could be incorporated into the copper production system. |
