| Abstract: | This paper researchs the influnte of Mn~2+ concentration in the electrolyte of zinc electrolysis on the structure and the formation mechanism of MnO_2 deposit on the anode. on the protection of lead anode, and on the quality of zinc cathode. The results shows that Mn~2+ in ZnSO_4 eleetrolyte shobld be kept at 3-5g / L, and that the equilibrium of Mn~2+ in the system should be kept. |
