The RapidSX™ platform is an accelerated solvent-extraction (SX) based separation technology for the separation of critical and other metal feedstocks. With the early stage support from the United States Department of Defense’s (US DoD) US Army Research Laboratory (ARL) program, RapidSX™ was successfully demonstrated using a pilot-scale SX circuit for the separation of rare-earth elements (REEs) derived from both light REE (LREE) and heavy REE (HREE) feedstocks.
The RapidSX™ technology combines the time-proven chemistry of SX — the international REE industry’s standard commercial separation technology, currently used by 100% of all REE producers worldwide for bulk commercial REE separation — with a proprietary column-based platform, which significantly reduces time to process completion and plant footprint, through a significant reduction in the numbers of processing steps required.
The work to date indicates the potential for significant technical and economic efficiencies for producing commercial-grade REE oxides (REOs).
COMPETITIVE ADVANTAGES OF RAPIDSX vs. CONVENTIONAL SX
Based on previous pilot-scale test work done by IMC and current expectations:
The RapidSX™ technology is being developed for the cost-effective, bulk/commercial separation and purification of Rare-Earth Elements (REEs) — including both heavy REE (HREEs) and light REEs (LREEs) — for the production of REE Oxides (REOs), in addition to other critical metals, such as Lithium (Li), Nickel (Ni), and Cobalt (Co) for Lithium-ion (Li-ion) battery materials.
