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.
