Element 25 Limited (E25) has filed two significant international patent applications for its battery-grade high-purity manganese sulphate monohydrate (HPMSM) production process.
E25 has filed patent applications under the Patent Co-Operation Treaty (PCT), claiming priority from Australian Patent Application(s) 2022903576 & 2022903573. These applications aim to protect two key manganese processing steps in E25’s flow sheet, crucial to its HPMSM process advantages, such as reduced energy consumption compared to roast reduction processing and reduced reagent consumption compared to traditional neutralisation.
The process involves separating waste residues into suitable forms in existing industrial processes, thereby reducing or eliminating waste disposal requirements.
Compared to existing producers, these advances allow the E25 process to claim industry-leading low carbon intensity while competing on cost in target markets.
Element 25 has developed a cutting-edge processing flowsheet for converting Butcherbird manganese concentrate into HPMSM, a crucial raw material for lithium-ion battery manufacturing. This reduces energy consumption, eliminates waste, and has the lowest carbon intensity globally.
The process provides a roadmap for increasing volumes of ethically sourced, traceable, and transparent HPMSM supply to US markets. Element 25 is building a one-of-a-kind processing facility in Louisiana to generate up to 135Kt of HPMSM per year for US electric vehicle (EV) supply chains.
E25 anticipates that its patent applications will be processed in 2024.
