ReElement Technologies, a US rare earth elements and critical mineral refiner, has received a letter of intent worth up to $150 million from the US Export-Import Bank to expand its rare earth refinery in Indiana. ReElement's investor, US Resources Corp, said on Monday that the funding from the US export credit agency will support the expansion of ReElement's Marion Advanced Technology Center to enhance its capacity to refine 99.5% rare earth oxides and compounds, including neodymium, dysprosium, terbium, samarium, yttrium, and gadolinium. The company owns and operates a 700 m² commercial validation facility in Noblesville, Indiana, for producing rare earth oxides and critical battery elements.
