| Abstract: |
| Zinc, indium and germanium were separated from hard zinc by vacuum distillation. The effects of distillation temperature and time on distillation rate, enrichment ratio, and component of condensate were investigated. The results show that the optimum conditions include distillation temperature of (900±20)℃, distillation time of 60 min, vacuum pressure of ≤1 000 Pa, and residual pressure of ≤800 Pa. |
