CMI researchers at Oak Ridge National Laboratory and Idaho National Laboratory conducted the activity for this highlight
Innovation
Novel diglycolamide (DGA) extractants enable high-throughput REE separations with significant reductions in reagent and equipment requirements.
Achievement
CMI industry partner Marshallton Research Laboratories has licensed a new technology for REE separations using DGA extractants.
Significance and Impact
- DGAs have superior selectivity among light REEs and do not require acid/base consumption typical of current industrial separation methods, potentially resulting in significant cost savings.
- The license grants Marshallton the right to perform research and development to make and use the DGA extractants.
- Next steps: Demonstration of a REE solvent extraction separation flowsheet, opening the door to a full commercial license and implementation.
Hub Target Addressed
Licensing of this technology achieves the FA1 Hub-level goal for industry adoption of a CMI technology that diversifies the supply of REE.
