DOE Announces $6.9 Million for Research on Rare Earth
Jun 09, 2017 · The U.S. Department of Energy''s (DOE) Office of Fossil Energy today announced it is investing $6.9 million in rare earth element (REE) research through two funding opportunities.DOE announced today that three projects have been selected to receive approximately $3 million for research aimed at producing salable rare earth elements (REEs) from domestic coal and coal byproducts.
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. Scandium and yttrium are considered rareearth elements because they tend to occur in the same ore deposits as the lanthanides and
Rare earths: industrial technology Introduction As this group has 17 kinds of elements, the appliions of rare earth elements are diversified: compounds from chloride 46% purity and 99.9999% of single rare earth oxides. The products are various. Details of their separation methods and smelting process are as follows.
