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

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.

(PDF) Separation of copper and zinc from waste acidic

The flowsheet appears as two main boxes colutrms which follow a similar step for the separation and recbvery of copper and zinc respectively. Beginning with the adjust of pH using Ca(OH)2, it follows a solid/liquid separation of the iron hydroxide precipitated, then removal of copper and zinc is achieved by using the resins described in this work.
