Abstract

This article discusses modern methods of purifying table salt from the Bakhyt-Tany deposits. Currently, the demand for various methods of production and processing of table salt is increasing. Therefore, high-quality purification of table salt and its effective use is one of the urgent tasks. As an object of study, salts were taken from the Bakhyt-Tany deposit, located in the Sozak district of the Turkestan region. The main goal of the scientific work is to study methods for purifying and processing sodium chloride from impurities. Modern analytical methods were used during scientific research. To determine the physicochemical properties of table salt, PEM JSM 6610 LV, X-ray microanalysis Inca Energy-450, energy dispersive system-fluorescence spectroscopy, IR-Fourier spectrometer were chosen. As a result of the research work, it turned out that using only the lime-soda method itself, it is possible to purify salt from calcium and magnesium ions up to 90-93%. It has been established that when using the phosphate method of purifying a saline solution, the degree of purification from calcium and magnesium ions increases to 95-97%. To further increase the degree of purification, it was recommended to first purify the solution using the lime-soda method, and then purify the solution using the phosphate method. It has been established that with this method the degree of purification can be increased to 99%.
