Test work using Infinity Lithium’s (INF) patent-protected Li-Stream RPK process has confirmed 90 per cent lithium recoveries from run of mine (ROM) to product.
Concurrently, the company has announced the successful production of battery-grade lithium hydroxide.
Infinity reported significant improvements in processing recoveries at its San José project, which not only offer potential production enhancements but also provide environmental and economic benefits.
The Li-Stream RPK process accelerates the ROM-to-Product flowsheet, eliminating several unit operations, including beneficiation, calcining, and roasting, while also generating energy for various processing stages.
The company’s subsidiary, INFGT, finalised the first-stage locked cycle test work to confirm the material improvements in recoveries and successful production.
Infinity’s Technical Advisory Committee has focused on improving process performance, operating costs, complexity, energy efficiency, and environmental impact.
“The process advancements will significantly improve the project in response to the demands we have been gathering from the people of Cáceres and the authorities, making it more efficient and sustainable,” INF’s Spanish subsidiary Extremadura New Energies CEO Ramón Jiménez said.
Infinity Lithium engaged a team that included Chief Process Engineer Dr David Maree, advisory group Chemprocess, and lithium consultancy services group Lithium Consultants Australia (LCA) to design and model the process.
They conducted extensive test work in collaboration with Simulus Laboratories, and further tests will continue in the coming weeks.
“The advancement of novel applications for hard rock lithium conversion to battery grade lithium chemicals is progressing globally in response to ESG, economic and demand factors.” INF CEO and Managing Director Ryan Parkin said.
“The extraordinary results achieved can significantly improve San José and lead European production into a new era for lithium mica applications.”
