Lithium is typically extracted from lithium-containing brine deposits or hard-rock mineral deposits. In the case of brine deposits, the lithium-rich brine is pumped to the surface and concentrated through evaporation in large ponds. The concentrated lithium solution is then further processed to remove impurities and isolate the lithium. For hard-rock mineral deposits, the lithium is extracted through a process of crushing, grinding, and then either leaching or roasting the ore to extract the lithium. The extracted lithium is then further refined to produce lithium compounds suitable for various applications. **
