| Abstract: |
| The effect of tannin, which is existed on the ZnSO_4 solution, on zinc electrolysis current efficiency are studied based on the analysis of datas coming from our Mine's plant practice, the results show that the tannin on the ZnSO_4 solution is easily removed on oxidizing medium and under high temperature, so it has no harm on zinc electrolysis and couldn't decrease the zinc electrolysis efficiency. |
