CMI Project 1.1.7 Improving beneficiation efficiency via preferential breakage and physical separation

This project is directed toward improving rare earth recovery at the Rare Element Resources (RER) Bear Lodge project while also increasing process energy and water use efficiency. Studies will explore preferential breakage using high pressure grinding roll systems and stirred milling, possibly paired with sortation and flotation. Potentially, the project will identify the combined impact of using these new and developing techniques in combination for the benefit of rare earth production in the United States.
