01-10-2016· Rare earths are actually not rare to exhibit a broad geographical distribution. The average levels of REEs in the earth's crust range from 150 to 220 ppm (ppm) which exceed the level of many other metals mined for industrial use (e.g. copper: 55 ppm and zinc: 70 ppm) (Long et al., 2010).Nonetheless, establishing and maintaining a reliable supply chain of REEs are of great concern

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.
