Abstract

PURPOSE:To recover MnO2 and Zn efficiently and simultaneously by an electrolyzing method by electrolyzing an electrolyte contg. Zn ions, Mn ions and free sulfuric acid respectively at prescribed concns. by using Al cathode plates electrodeposited with Zn by an ordinary zinc electrolyzing means. CONSTITUTION:An electrolyte contg. 5-80g/l Zn<2+>, 20-80g/l Mn<2+>, and 1- 60g/l free sulfuric acid is electrolyzed particularly by using Al plates electrodeposited beforehand with Zn by an ordinary zinc electrolyzing method as cathode plates under the following conditions: It is electrolyzed under the conditions of 75-95 deg.C, and 89-300A/m<2>, more particularly 80-120A/m<2> anode current densities to electrodeposit MnO2 on the anode and Zn on the cathode respectively. As a result, not only the MnO2 of high commercial value is extracted recovered simultaneously at the same electric energy as that in the case of extraction and electrolysis of Zn, but also the work with higher electric current efficiency is made possible.
