Rational use of mineral resources is becoming an important task for the development and economic growth of Kazakhstan. The purpose of the research was to study the state of salt-containing raw materials to determine the prospects for rational use of mineral resources of the Dzhaksy-Klych Deposit, one of the salty halite lakes of the Aral region. Exploration studies have shown that the Deposit is layered, where the halite layer is underlain by a sulfate layer: astrakhanite, mirabilite, tenardite, located on a layer of silt, the bed of salt deposits is dark brown clays, less often - clay Sands. Mineralogically, the halite formation is represented by, %: halite –90-96, epsomite -1,2-2,6, mirabilite -0,2-1,9, gypsum-0,2-1,4. The production of table salt results in waste containing 65.5% chlorides, 24.5% sulfates, 6.5% sodium carbonates, and 3.5% sodium silicates, which can be used for pharmaceutical and medical purposes. Bottom silty mud by its origin and chemical composition belongs to the mainland silt-sulfide type and can be used for Spa and balneological treatment. The reserves of sulphate salts in the field are significant, with the average thickness of the sulphate reservoir in the southern basin being 0.87 m, and in the Northern basin 0.91 m. Intergranular and surface brine containing sodium and magnesium chloride-sulfate salts is of particular interest. Analysis of the state of mineral resources of the Dzhaksy-Klych Deposit revealed prerequisites for expanding the range of opportunities for using salt-containing raw materials. A promising direction for the development of the mineral resource base is the production of soda based on sodium chloride, as well as the production of a commercial product based on sodium sulfate and magnesium chloride. Microbiological examination showed the presence of non-pathogenic forms of halophilic bacteria in the salt-containing raw materials, which indicates safety for use in pharmaceutical and medical practice. In the Aral sea region, there is every reason for the development of the cosmetology industry, where a wide range of cosmetology and pharmaceutical products can be produced based on a combination of salt-containing and local vegetable raw materials.
