Sep 02, 2019· When reporting on REE, companies may, at times, use a broad subdivision of the group into Light Rare Earth Elements (LREE), Heavy Rare Earth Elements (HREE) and, occasionally, Medium Rare Earth Elements (MREE). These are not formal groupings and are not applied consistently across the industry.
A rareearth element (REE) or rareearth 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.
The proposed USbased REE plant has a small footprint and capital costs that are a fraction of the traditional REE mining and processing facilities, according to Medallion. "This provides a quick pathway to production of rareearth products for domestic markets," the company said.
