    Lead concentrates that contain silver are first roasted, which is a precursor state to silver smelting used to drive off sulfur compounds in the ore, and this produces lead bullion. The impurities in lead bullion include arsenic, tin,and silver, and this silver is then removed through the Parkes process, named after Alexander Parkes, a UK metallurgist who patented it in 1850.

    Five Things You Didn't Know About Smelting

    Smelting, on the other hand, uses heat and reducing substances to cause a chemical change to occur, so that a metal can be extracted from its ore. The original material, usually a metal ore, is heated with a source of carbon, such as charcoal, or a high carbon-content fuel called coke. The carbon combines with the oxygen in the ore to form carbon dioxide or carbon monoxide, which then escapes
