- Successful impurity removal tests
- Opportunity identified for rubidium by-product recovery
- Next steps include producing high-purity caesium compounds
Full Summary
Patriot Battery Metals Inc. has announced the successful completion of bench-scale testwork for caesium extraction from pollucite concentrate, achieving over 97% recovery using sulphuric acid leaching. The tests also demonstrated efficient removal of key impurities like aluminum, with no significant loss of caesium. Additionally, the program identified a potential opportunity to recover rubidium from one of the waste streams. The next steps involve producing gram quantities of high-purity caesium compounds, including Cs-sulphate, Cs-carbonate, and Cs-formate, with results expected in Q4 2026. The company is also collaborating with Koch Technology Solutions to explore advanced processing pathways for caesium extraction.
