Caldera Holding, the owner and developer of Missouri’s Pea Ridge iron mine, has entered a nonexclusive research and development licensing agreement with Oak Ridge National Laboratory to apply a membrane solvent extraction technique, or MSX, developed by ORNL researchers to mined ores. MSX provides a scalable, efficient way to separate rare earth elements, or REEs, from mixed mineral ores.
The MSX technology was pioneered at ORNL by researchers in the Department of Energy’s Critical Materials Innovation Hub, or CMI, led by Ames National Laboratory. The inventors, Ramesh Bhave and Syed Islam of ORNL’s Chemical Sciences Division are named in 26 inventions and five active licenses related to the recovery of REEs.
