摘要:
A process for recovering zinc and manganese dioxide from material containing zinc and manganese compounds, includes leaching the material to provide an aqueous solution containing manganese and zinc ions, electrolyzing the solution in one electrolytic cell with conditions inhibiting the formation of manganese dioxide and favoring the deposition of zinc, and electrolyzing the solution in another electrolytic cell with conditions favoring the formation of manganese dioxide. Zinc is removed from the one electrolytic cell and manganese dioxide is removed from the other electrolytic cell.
