Lead smelting - Wikipedia

Galena, the most common mineral of lead, is primarily lead sulfide (PbS).The sulfide is oxidized to a sulfite (PbSO 3) which thermally decomposes into lead oxide and sulfur dioxide gas.(PbO and SO 2) The sulfur dioxide (like the carbon dioxide in the example above) is expelled, and the lead oxide is reduced. Anglesite, Cerussite, Pyromorphite, Mimetite and Wulfenite are other lead ores.
