ABSTRACT:
Zinc is separated from a zinc-copper alloy, in particular, brass scrap, by reacting the alloy with an aqueous alkali metal bisulfate to dissolve zinc selectively with respect to copper. Zinc is recovered from the resulting solution by precipitation in the form of an insoluble zinc compound, namely, zinc carbonate or zinc hydroxide.
