METHOD AND APPARATUS FOR SEPARATING AND RECOVERING RESOURCE FROM WASTE DRY CELL AND RECOVERED SUBSTANCE

Japanese Patent JP2015206077

A

PROBLEM TO BE SOLVED: To provide a method and an apparatus for separating and recovering a manganese component and a zinc component contained in a waste dry cell from the waste dry cell, and recovered substances.SOLUTION: A manganese dry cell and/or an alkali manganese dry cell are/is selected from waste dry cells. The selected dry cell is crushed and sieved to obtain a particulate matter, from which an acid solution leaches manganese and zinc to obtain a leachate containing the manganese and zinc and a leach residue containing manganese. After the leachate and the leach residue is subjected to solid liquid separation, the separated leachate is treated with ozone to obtain a manganese-containing deposit and a zinc-ion-containing solution. By subjecting the manganese-containing deposit and the zinc-ion-containing solution to solid liquid separation, a manganese component contained in the waste dry cells is separated and recovered as the leach residue and the manganese-containing deposit, a zinc component contained in the waste dry cells is separated and recovered as the zinc-ion-containing solution.
