| Abstract: | Some metal ions, such as cadmium ion, cobalt ion and arsenic ion have the significant influences on the long period zinc electrowinning process. The roles of them in the process for the long period zinc electrowinning were briefly introduced: cadmium ion has a greater impact on the quality of zinc precipitation; for reducing the current efficiency of zinc, cobalt ion plays more obvious role, whereas arsenic ion is the most severe influencing factor. Moreover, the effects of the similar ions on the long peri... |
