| Abstract: |
| Recycling of copper slag used for dechlorination in zinc hydrometallurgy was investigated. The optimum recycling conditions include L/S of 3︰1, dosage of calcium oxide of 4%, and reaction time of 1 h. Content of copper, Cl- and Ca2 in recycled copper slag is 57%~59%, 1.5%~2.0%, and 6%~7% respectively with no effect on dechlorination and advantage of recycling. |
