ChemX begins early-stage commissioning of HiPurA® pilot plant
ChemX Materials (ASX: CMX) has begun early-stage commissioning of the leach circuit within its HiPurA® high purity alumina (HPA) pilot plant in WA. The leach circuit is part of ChemX’s flowsheet and comprises the first part of the patented HiPurA® purification process. It takes the aluminous chemical feedstock and sufficiently upgrades its purity for the solvent extraction stage. The HiPurA® process produces HPA and high purity alumina cathode precursor salts for lithium ion batteries. It can produce above 4N (99.99%) pure HPA and is low in energy consumption compared to alternative technologies. ChemX received an Australian patent for this technology in January 2024 and it provides intellectual property protection as it seeks to commercialise the technology globally.
