Аннотация:This review briefly discusses acidic, basic, and saline methods of lithium salt recovery from mineral spodumene, methods of processing natural chloride brines by alternative removal of attendant elements of the first and second groups as well as the recovery of lithium salts by using DALH-Cl based on Al(OH)3. A suggested hypothesis provides the explanation for some unusual properties of the material by the influence of hydrogen bonds and dissociation of Al(OH)3 in an aqueous medium.
