It seemed likely that these might have been undiscovered elements and the hunt was on. Sure enough, new el 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. Lead (pronounce: "/'lɛd/") is a chemical element.
