Lead

Lead is present in ores such as galena (cubic lead sulfide, PbS), anglesite (rhombic lead sulfate, PbSO 4), cerussite (rhombic lead carbonate, PbCO 3), minim (a form of lead oxide with formula Pb 3 O 4), and other minerals. Galena is the most important source. Lead also accumulates with Zn and Cd, Fe and other metals in ore deposits.
