• Rare-Element Granitic Pegmatites Rare Earth and Critical

    2016-1-1 · Rare-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.Rare minerals from pegmatites AMNH,2021-12-19 · Rare minerals from pegmatites Part of Hall of Planet Earth.
