This work investigated the effects of the electrolysis conditions on anodic deposition of MnO₂ on manganese oxide coated titanium electrode to examine a possibility of production of electrolytic manganese dioxide from zinc electrowinning solutions. The preparation conditions of the electrode, the current density, the bath temperature, and the others were investigated to know the influences on the crystallographic structure, surface morphology, and current efficiency of the deposited MnO₂.
