Kazakhstan is a country with an arid climate, where a number of salt lakes are located, where industrial production of edible salt is carried out. Due to the increase in the volume of salt production for export needs and the possibility of expanding the scope of its use for medical and cosmetic purposes, new layers and deposits of salt are being developed. The purpose of this study was to refine the characteristics of Dzhaksy-Klych Deposit salts using FTIR spectroscopy. The objects of the study
more » ... bjects of the study were samples of salt-containing raw materials selected from different sites of Dzhaksy-Klych Deposit. Based on the conducted research, it can be predicted that when the Aral sea turns into a chloride salt lake, the main sediment will be sodium chloride, with additional formation of salt deposits from sodium sulfate, calcium or magnesium. The results obtained provide useful information about the mineralogical composition of the Aral sea region salts, which complements the knowledge about the composition of minerals. The results of FTIR analyses show that the samples of salts of lake Dzhaksy -Klych are represented by the following compositions: halite, astrakhanite, hexahydrate, gypsum, mirabilite, and the absence of toxic substances in the studied salt samples confirms their suitability for use in food, pharmaceutical and cosmetic purposes.
