Smelting Silver Oreextraction Of Copper From Copper Sulphide

lead is extracted from its ore by reduction with carbon. later, a chemical such as copper(ii) sulfate is added and the zinc ore now floats and is skimmed off. sulfur dioxide gas can then be cleaned and used to make sulfuric acid. lead and zinc are almost immiscible just above their melting points; silver is much more
