Lead

The main lead bearing mineral is galena (PbS), which is mostly found with zinc ores. Most other lead minerals are related to galena in some way; boulangerite, Pb 5 Sb 4 S 11, is a mixed sulfide derived from galena; anglesite, PbSO 4, is a product of galena oxidation; and cerussite or white lead ore, PbCO 3, is a decomposition product of galena.
