| Abstract: |
| Cobalt and copper were recovered by hydrometallurgy process from copper converter slag after multielement and phase analysis. The effects of particle size, initial sulfuric acid concentration, temperature, ratio of liquid to solid, time, stirring speed, ventilation speed and other factors on leaching rate of copper and cobalt were examined. The results show that total copper recovery rate is over 95%, cobalt and iron total recovery rate is over 98% with sulfuric acid leaching after screening coarsness copper concentrate. |
