Rare Element Pegmatites - Prospecting Exploration Minerals

Rare element pegmatites are mineralogically complex and enriched in lithophile and incompatible elements, such as beryllium, lithium (spodumene and petalite), rubidium (lepidolite), cesium (pollucite), tin (cassiterite), tantalum and niobium (Ta-oxide minerals), rare-earth elements, and uranium. The concentration of these elements may be highly enriched in pegmatites

Mining a Pegmatite Actforlibraries

Mining a Pegmatite. Earth Science. Pegmatites come in two flavors simple and complex, or dirty. The complex pegmatites are the source of many rare minerals used both as gemstones, and rare metal ores. Pegmatites being relatively small in comparison to other mineral deposits lend themselves to small mining operations. Some of them can even be mined by one man, although I can’t see why one man ...

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. Growth in the demand for Li-based batteries has ...

Rare-earth element - Wikipedia

Economically viable pegmatites are divided into Lithium-Cesium-Tantalum (LCT) and Niobium-Yttrium-Fluorine (NYF) types; NYF types are enriched in rare-earth minerals. Examples of rare-earth pegmatite deposits include Strange Lake in Canada, and Khaladean-Buregtey in Mongolia.

Rare-earth mineral - Wikipedia

A rare-earth mineral contains one or more rare-earth elements as major metal constituents. Rare-earth minerals are usually found in association with alkaline to peralkaline igneous complexes, in pegmatites associated with alkaline magmas and in or associated with carbonatite intrusives. Perovskite mineral phases are common hosts to rare-earth elements within the alkaline complexes.
