galena lead tantalum

Lead Tantalate AMERICAN ELEMENTS

Lead occurs naturally as a mixture of four stable isotopes: 204 Pb (1.48%), 206 Pb (23.6%), 207 Pb (22.6%), and 208 Pb (52.3%). Lead is obtained mainly from galena (PbS) by a roasting process. Anglesite, cerussite, and minim are other common lead containing minerals. Lead does occur as a free element in nature, but it is rare.
