01/01/2016Rare-element granitic pegmatites represent highly concentrated sources of rare metals, including Li, Rb, Cs, Be, Sn, Nb, Ta, Zr, Y, REE, and U. In today's markets, pegmatites are the principal sources of Ta, and one pegmatite (Tanco, Canada) is the sole commercial producer of Cs for use as deep drilling fluid in the form of Cs formate solution.

01/03/2011Rare-earth elements are not really very rare. They are as common in the Earth's crust as tin, lead and zinc. They were named 'rare earths' when they were discovered in the 19th century because they were found in scarce minerals.
