Enhancing and Diversifying Supply

As CMI begins its third phase of operation in 2023, the CMI focus area Enhancing and Diversifying Supply (which was known as Diversifying Supply during CMI Phase I and Phase II) will conduct research around the themes of Advancing Mineral Characterization and Beneficiation and Innovative Separations and Recoveries.
