Critica Limited says it has achieved a major improvement in processing of rare earth material from its WA Jupiter project during pilot beneficiation work in Vietnam. According to the company’s updates reported by multiple outlets, the rare earth feed is upgraded 14-fold, resulting in a concentrate grade of about 3% TREO (total rare earth oxides). The process also rejects around 95% of the original feed mass, indicating that a large portion of non-rare-earth material is removed during beneficiation.
While the reporting focuses on the pilot results, the articles frame the development as a “breakthrough” in refining an upgrade code for the project rather than a full-scale production outcome. The outlets agree on the key metrics—14-fold improvement, 3% TREO concentrate, and 95% mass rejection—at the Vietnam pilot stage. They do not provide additional detail on timelines, plant capacity, or whether further scale-up trials will replicate the results. Overall, the coverage presents the pilot beneficiation performance as an early step toward improving the quality of Jupiter’s rare earth feed for subsequent processing.
