CMI Project 1.1.5 Enhanced domestic extraction of platinum group metals, nickel, copper and cobalt from primary sources

This project will develop enhanced methods to extract platinum group metals (PGMs) as well as high value by products, such as nickel (Ni), cobalt (Co) and copper (Cu) from domestic U.S. sources.

CMI Project 1.1.6 Extraction of rare earth phosphate minerals from primary and secondary sources

This project will develop a cost-effective approach for the flotation of phosphate minerals containing rare earth elements (REE) sourced from conventional and unconventional sources including ores,

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.

CMI Project 1.1.9 Diversifying lithium supply from brines to hard-rock minerals: mechanochemical extraction of lithium at low temperature (MELLT) from α-Spodumenes

In the United States, brines are the primary source for lithium extraction. However, their long lead times and low lithium extraction yields limit their ability to meet the recent surge in demand.
