REE Separation

UIT is currently operating a large-scale hydrometallurgical pilot plant in Germany. Preliminary results, using proprietary technology, indicate the successful extraction of Nd/Pr and other REE, contained in a high-purity rare earth oxide (REO). UIT will continue to operate the pilot plant to produce REO from ore obtained at Rare Element Resources Bear Lodge Project in Wyoming. Once sufficient REO is produced, UIT will begin the separation test phase. The separation pilot plant test will utilize the enhanced proprietary technology to produce several products- a high-purity neodymium/praseodymium (Nd/Pr) oxide, lanthanum (La) oxide, and a mixed mid-and heavy rare earth concentrate. The enhanced process is expected to significantly reduce process steps and operating costs as well as further reduce environmental impacts and associated costs.
