Commercial Lithium Production and Mining of Lithium
By. Terence Bell. Updated on August 21, 2020. Most lithium is commercially produced from either the extraction of lithium-containing salts from underground brine reservoirs or the mining of lithium-containing rock, such as spodumene. Lithium production from clay sources is expected to become commercially viable, though perhaps not until …
