Zinc ash is a discarded material of galvanizing plant and consists mostly of oxidized zinc that forms on the surface of molten zinc metal in galvanizing pot. The ash is removed from the top of galvanizing baths by skimming or straining and discarded. Both hydrometallurgical and pyrometallurgical processes can be used for recovery of zinc from ash.
