抄録

The purpose of this study was the recovery and effective utilization of manganese component from the used battery.<BR>As manganese was included in the anode mixture for the cell, it was advisable to separate only the mixture from the used battery.<BR>It was found that a hammer crusher was better in regard to the above purpose than the cutter mill, because part of the metallic Zn tended to be ground down in the case of the latter and be included in the pulverized fine powder with the anode mixture powder. The complete dissolution of Mn from the fine powder was difficult by sulfuric acid leaching but possible when water leaching with blowing SO₂at room temperature was performed. In the first step treatment of the leaching solution, all of Fe could be eliminated as the precipitation by adjusting pH of the solution below 6 and then both Mn and Zn could be precipitated completely in adjusting the pH above 10 after the elimination of Fe component.<BR>It was possible to form the manganate which may be utilized as a soft ferrite material by heating of the prepicitation products obtained above pH 10.
