Abstract: The purpose of the research is to create a technology for processing hydromineral raw material into products of lithium salts and rare earth elements, as well as to develop a highly efficient technology for production of lithium, lithium compounds and rare earth elements of the Aral region. The chemical and mineralogical composition of the hydromineral raw material of the Aral region lakes has been studied by the method of precipitation. The conditions for obtainment of lithium concentrates have been studied. The conditions for lithium minerals concentration and production of concentrates for lithium chloride extraction have been investigated. Purification of lithium concentrates off ions of calcium and magnesium, as well as effective methods of lithium precipitation in the form of lithium carbonate have been studied. The extraction methods for processing lithium-containing sediments and sorption methods of lithium extraction from brines have been investigated. Water-salt systems for the directed search of effective methods for obtainment of lithium salts from brine and sediments of salt lakes have been studied.
