Abstract
Procedure for recovering potash and zinc oxide from potassium zinc solutions, characterized in that a selective solvent for potash, miscible with water, is added to the zinc solution; the zinc oxide precipitate thus obtained is filtered; and the mother liquor is treated to separate the potash solution and said solvent.
