Aug 21, 2020 An Overview of Commercial Lithium Production. 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 2022.
Aug 31, 2017 The most important commercial process is the extraction of lithium by roasting with sulfuric acid. This process is described by Ellestad and Leute. Lithium has also been extracted from its ores by chlorination. Many processes have been proposed whereby the ore is roasted with a chloride salt of potassium, sodium, or calcium.
