Exoben's cutting-edge refinery technologies produce ultra-pure lithium hydroxide, carbonate, and metal—powering next-generation batteries and energy solutions

Refinery Technologies​

Exoben’s advanced refinery technologies produce high-purity lithium hydroxide, lithium carbonate, and lithium metal through sophisticated chemical and electrochemical processes. These technologies are essential for powering next-generation batteries and other high-performance applications.

Lithium Hydroxide Production​

Lithium carbonate is converted to lithium hydroxide using calcium hydroxide. The process involves purification, crystallization, and drying to achieve the high purity needed for advanced lithium-ion batteries, especially in electric vehicles.

Lithium Carbonate Production​

Lithium carbonate is extracted from brines and precipitated using sodium carbonate. It is then purified through filtration and drying to meet high purity standards for use in batteries, ceramics, glass, and pharmaceuticals.

Lithium Metal Production​

Lithium carbonate is extracted from brines and precipitated using sodium carbonate. It is then purified through filtration and drying to meet high purity standards for use in batteries, ceramics, glass, and pharmaceuticals.

Advanced Refinery Technologies

Ion Exchange & Absorption:

Selectively captures lithium ions, enhancing recovery and purity.

Membrane Technologies

Uses nanofiltration and electrodialysis to concentrate and purify lithium solutions efficiently.

Solvent Extraction
