    The Parkes process is a pyrometallurgical industrial process for removing silver from lead during the production of bullion.It is an example of liquid–liquid extraction.. The process takes advantage of two liquid-state properties of zinc.The first is that zinc is immiscible with lead, and the other is that silver is 3000 times more soluble in zinc than it is in lead

    The Parkes zinc-desilvering 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 reverberatory “softening” furnace, where
