| Abstract: |
| The comprehensive utilization of cobalt slag coming from two-stage purity residue treatment process in Northwest Lead-Zinc Smelter are studied. After adopting acid leaching, iron removing and cobalt depositing process, Zn, Co, Cd are separated successfully, furthermore, the products such as zinc sulfate, alkalinity cobalt carbonate, and sponge cadmium are produced, the total recovering rate of Zn, Co, Cd is 99.3%, 77.0% and 96.5%, respectively. |
