CMI Project 3.2.6 Selective separation and recovery of rare earth elements using Membrane Solvent Extraction (MSX)

In this project, novel Membrane Solvent Extraction (MSX) technologies will be evaluated based on the previous experience and in-depth understanding of MSX for rare earth element (REE) extraction from various feedstocks to recover high purity heavy rare earth directly from intra-lanthanide separations. The effect of process conditions such as type of extractant, different extractants (cationic and neutral extractants), type of extractant diluent, different feedstocks, feed solution concentration, feed/strip pH, extractant composition, and feed/strip residence time will be investigated to achieve high extraction rates and separation factors for dysprosium (Dy) over other metal constituents in respective processes. Preliminary Techno-Economic Analysis (TEA) will be performed to assess the cost-effective of the MSX process.
