Lithium Ark’s patented process transforms lithium chloride (LiCl) into battery grade lithium hydroxide (LiOH) – efficiently, cleanly and economically. Our process eliminates traditional emissions-intensive steps while maintaining the highest quality standards and reducing overall production costs and capital expenditure.
Our process replaces complex, reagentintensive refining with a simple, circular salt system.
It lies in its reciprocal salt chemistry, which uses the natural balance between lithium and potassium salts to separate and purify lithium efficiently from lithium chloride.
Our process achieves low OPEX and CAPEX through simplicity and efficiency: fewer reaction steps, less energy use, and fully recyclable reagent result in a cleaner process that costs less to build and run.
It captures nearly all lithium – above 99% – while consistently producing battery-grade quality.
Our process has been independently validated by Kemetco, GEA and IBZ at TRL-5 level.
These independent test confirmed the process´s stability, high lithium recovery, and ability to consistently produce battery-grade material from different feedstocks; using offshelf equipment.
Our patented circular chemistry instead of consuming reagents, it recycles potassium within the process, reducing waste, cost, and environmental impact.
The process avoids the use of soda ash, a major CO2 source in conventional refining, achieving a cleaner and more sustainable operation.
Lithium Ark overcomes these challenges with a patented circular process that combines low cost, scalability, sustainability, and superior economic results in one proven solution.
Revolutionary lithium refining process that delivers environmental and economic advantages.
