METHOD OF PRODUCING ZINC ALLOY POWDER FOR CELL AND ALKALINE CELL WITH THE ZINC ALLOY POWDER

摘要

In order to clean a zinc alloy powder for an alkaline cell, the zinc alloy powder is dispersed in water or an acid or alkaline aqueous solution used as a medium under agitation so that impurities which adhere to the surfaces of the zinc alloy powder are separated and removed as suspended substances. Magnetic impurities mixed in the zinc alloy powder are removed by magnetically sorting the powder before or after the treatment using a medium, thereby improving the cleaning circuit.
