| Abstract: |
| Copper acidic slag from zinc hydrometallurgy was comprehensively recovered applying selective leaching and extraction. Effects of ammonia water concentration, oxidant dosage, leaching time, and leaching temperature on leaching rate were investigated by single factor experiment and expanding test. The results show that leaching rate of copper and zinc is 96.5% and 86% above respectively, leaching rate of iron and lead is 3% and 1.2% below respectively. Sharply reduction of cost is achieved. |
