    The Parkes zincdesilvering process is the most widely used pyrometallurgical method of refining lead bullion. As in smelting, the lead is first melted and again allowed to cool below the freezing point of copper, which crystallizes and, along with any remaining nickel, cobalt, and zinc, is removed by skimming. The lead mix then passes to a
