    • Separation of zinc from a zinc-copper alloy - Chempro ...

    In accordance with the invention, zinc is separated from a zinc-copper alloy by reacting the alloy with an aqueous alkali metal bisulfate to dissolve zinc selectively with respect to copper. The zinc preferably is recovered from the resulting solution by precipitation in the form of an insoluble zinc compound. The solid residue remaining undissolved after the reaction with bisulfate contains the copper present in the alloy,
