| Abstract: |
| The three main methods for high purity zinc preparation,including electrolytic method,vacuum distillation,zone refining,are summarized and compared in this paper.They play different roles in the purification of zinc.The technological conditions of electrolytic method is easy to control,but it requires a great deal of energy and the effect of purification is relatively poor;Vacuum distillation method is effective for separating the impurities and has an efficient use of energy,but it is basically impossible ... |
