Lead has been known since ancient times. It is sometimes found free in nature, but is usually obtained from the ores galena (PbS), anglesite (PbSO 4), cerussite (PbCO 3) and minum (Pb 3 O 4). Although lead makes up only about 0.0013% of the earth's crust, it is not considered to be a rare element since it is easily mined and refined.

Elemental lead is found in nature sparingly. Lead is present in ores such as galena (lead sulphide, PbS), anglesite (lead sulphate, PbSO 4), minim (a form of lead oxide with formula Pb 3 O 4), cerussite (lead carbonate, PbCO 3) and other minerals. The abundance of lead in the Earth's crust is estimated to be between 13 and 20 parts per million. It ranks in the upper third among the elements in terms of its abundance.
