Rare-earth element - Wikipedia

A rare-earth element (REE) or rare-earth metal (REM), as defined by the International Union of Pure and Applied Chemistry, is one of a set of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides, as well as scandium and yttrium. Scandium and yttrium are considered rare-earth elements because they tend to occur in the same ore deposits as the lanthanides and ...

Scientists Just Found a Way to Extract Rare-Earth Elements ...

06/03/2019  Even though the elements only make up about 0.1 percent of phosphate rock, the amount of waste produced means the annual production of rare earth oxides could be almost doubled, in theory. REEs are actually quite plentiful in Earth's crust, despite the "rare" in the name - but they're widely dispersed and difficult to get out, both practically and economically.
