Rare earth metals, including the lanthanide series, scandium, and yttrium, are critical components in permanent magnets, electric vehicles, smartphones, and more. The elements occur naturally as mixtures in ores and must be purified prior to use. However, the mining and separation of the mineral ore is challenging, in addition to being energy ...
Rare earth elements : industrial technology, smelting process Metalpedia. Rare earths: industrial technology. Introduction. As this group has 17 kinds of elements, the applications of rare earth elements are diversified: compounds from chloride 46% purity and 99.9999% of single rare earth oxides. The products are various.

WASHINGTON, D.C. The U.S. Department of Energy today awarded $19 million for 13 projects in traditionally fossil fuel producing communities across the country to support production of rare earth elements and critical minerals vital to the manufacturing of batteries, magnets, and other components important to the clean energy economy.
However, rare earth separations by conventional solvent extraction or ion exchange chromatography methods are time consuming, require substantial cost, and are unsustainable. Photochemical based separation has been examined as a promising preprocessing step to separate redox active rare earths, especially europium, from mined ore mixtures. New ...
