Abstract

Zinc granules are dissolved in a weakly acidic ZnNi electrolyte while uniformly passing fine air bubbles through the bulk granules. An Independent claim is also included for a process for dissolving zinc granules in a weakly acidic ZnNi electrolyte of pH above 1.6 involving uniform passage of fine air bubbles through the bulk granules.
