Investigation of Azambur Mirabilite Deposit and Lake Water to Obtain Anhydrous Sodium Sulfate

Under the influence of environmental conditions, the article examines the change in the physical and chemical properties of the natural brine system containing sodium sulfate, which is located in Georgia, on the territory of the municipality of Sagarejo. To this purpose in November-June 2019-2020 the full chemical compositions of natural brine were studied at one-month intervals. The following ions were studied in brine: SO4 2-, Cl- , HCO3 - , CO3 2-, Na+ , K+ , Ca2+ and Mg2+.. In water samples, conductivity was also measured. The concentrations of the studied ions in the natural brine vary with the season, in particular, all the studied ions begin to decrease in the fall, sharply decrease in the winter, increase in the spring and significantly increase in the summer.
