Lithium Refining Using Crystallization
The global demand for lithium is skyrocketing, driven by increasing electric vehicle (EV) sales powered by lithium-ion batteries. However, pure lithium is not found in nature; it must be extracted and refined from liquid brines commonly found in salt lakes, oil field, geothermal brines, or from lithium-bearing minerals found in hard rock mines and some clay deposits.
The refining process isolates the lithium while removing contaminants and other chemicals to produce a pure, usable form of lithium. As lithium demand rises, so does the need for efficient, cost-effective lithium extraction and refining processes. Crystallization processes that are designed to form high purity lithium crystals by controlling how the crystal is
formed and grown have been proven to produce valuable battery-grade lithium products.

Our Clients
Lithium Refining Crystallization Systems
Years of know-how and experience to properly engineer the process to control the formation of the crystals in a manner that effectively separates the impurities. Each lithium source stream, either produced from lithium brines or hard rock, has its own impurity profile that requires unique design approaches. Crystallizers can be used to effectively remove contaminants from lithium sources to improve the lithium recovery. It is important to
work with an experienced crystallizer technology partner that provides the breadth of experience necessary to successfully address all challenges.
