Lithium extraction is the process of separating lithium from its sources, such as salt-flat brines or mineral ores, to produce high-purity lithium compounds. This can be done through various methods, including evaporation, acid leaching, and direct lithium extraction (DLE) techniques, which involve solvent extraction or adsorption to selectively capture lithium ions. The goal is to achieve a high concentration of lithium for use in battery manufacturing and other applications.
