| Abstract: |
| Zinc oxide dust bearing germanium was treated by atmospheric-pressure leaching process for high-efficient leaching of zinc and germanium. The effects of leaching temperature and time, sulfuric acid dosage, and ratio of liquid to solid on leaching rates of zinc and germanium were studied. The experimental results show that under condition of the optimum process parameters, zinc and germanium leaching rates can reach 96.92% and 89.72%, respectively. |
