RareX Limited announced their strongest metallurgical testwork results for the Cummins Range Rare Earths & Phosphate Project, achieving significant enhancements in flotation testwork and gallium extraction. The company reported a 9.5x upgrade in total rare earth oxide (TREO) recovery through SGS Lakefield's flotation tests and affirmed an effective gallium recovery route via Gega Elements' optimized acid bake and leaching method. These advances indicate the potential for a unified recovery circuit for rare earth elements, gallium, and scandium. The Cummins Range project, located in Western Australia, holds a substantial mineral resource base, contributing to RareX's strategic positioning in rare earth production.
Key Points
RareX Limited reported successful metallurgical test results from the Cummins Range Rare Earths & Phosphate Project.
Significant improvements were made in the flotation testwork by SGS Lakefield, achieving a 9.5x TREO upgrade.
Advanced mineralogical characterization identified monazite liberation grind size as a primary constraint on recovery.
Gega Elements confirmed near-complete gallium extraction using an optimized acid bake and water leaching process.
High extractions of REEs, scandium, and niobium were observed during leaching, indicating potential for an integrated multi-element recovery circuit.
The testwork supports an integrated flowsheet that recovers RE concentrates, gallium, and potentially scandium from a single processing circuit.
The project has a substantial mineral resource with a combined MRE totaling 524 Mt at 0.31% TREO and 4.6% P2O5.
The workstreams included conventional flotation beneficiation and an evaluation of a biologically driven nano-phosphate pathway.
