Lead rarely occurs naturally in nature and is can be found in ores, mainly with copper, zinc and silver. The principal lead mineral is lead sulfide (galena, PbS). Other common minerals are cerussite (lead carbonate, PbCO 3) and anglesite (lead sulfate, PbSO 4). Lead is refined from galena (PbS) by heating.
