Mineralische Rohstoffe - Advances Separation Technology of Critical Rare Earth Elements

Minerale Resources - Rare Earth Elements

RER (Rare Element Resources) engaged UIT to conduct a pilot plant campaign in February 2019 to verify, at pilot plant scale, all process steps from the hydrometallurgical process already validated to the final separation of Nd/Pr oxide. RER is pleased to announce additional significant progress on the previously announced third-party pilot scale testwork relating to its proprietary rare earth separation technology. This work is being conducted by Umwelt-und Ingenieurtechnik GmbH Dresden (“UIT”)

UIT is currently operating a large-scale hydrometallurgical pilot plant in Germany. Preliminary results, using RER’s proprietary technology, indicate the successful extraction of Nd/Pr and other rare earth elements, contained in a high-purity rare earth oxide (REO). UIT will continue to operate the pilot plant to produce REO from ore obtained at the Company’s Bear Lodge Project in Wyoming. Once sufficient REO is produced, UIT will begin the separation test phase, scheduled for the third quarter of 2019. The separation pilot plant test will utilize the Company’s 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, if successful, is expected to significantly reduce process steps and operating costs as well as further reduce environmental impacts and associated costs.
