Rareearth element Wikipedia
Though rareearth elements are technically relatively plentiful in the entire Earth's crust (cerium being the 25thmostabundant element at 68 parts per million, more abundant than copper), in practice this is spread thin across trace impurities, so to obtain rare earths at usable purity requires processing enormous amounts of raw ore at great expense, thus the name "rare" earths2019年1月4日 Rare earth elements are essential for modern life products and green technologies Recent supply constraints have boosted the development of rare earth projects after the price peak of 2011 The feasibility of a project depends on the definition of a processing route, which in turn depends primarily on the rare earth mineral, with monazite and bastnaesite Selective Extraction of Rare Earth Elements from Monazite Ores mined locally, differences in the rare earth element (REE) content may arise because the same metal ore deposits also occur in several other parts of the world The explanation of RE minerals in this chapter is primarily intended to show that the REE and byproduct from these minerals appear to have opportunities for industrial useRARE EARTHS PROCESSING2016年7月7日 Rare earths are relatively abundant in the Earth’s crust, but discovered minable concentrations are less common than for most other ores Bastnäsite deposits in China and the United States constitute the largest percentage of the world’s rare earth economic resources, while monazite deposits are found in Australia, Brazil, China, India, Malaysia, South Africa, Sri Lanka’s longneglected treasure, rare earths Daily FT
