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.
