SALT PROCESSING AT THE NAKHICHEVAN SALT DEPOSIT

One of the topical issues is the study of the formation conditions, geological structure, chemical composition and methods of development of the "Duzdag" salt deposit, formed in the Babek region of the Nakhchivan depression on the territory of Azerbaijan, in order to meet the salt needs of the population. The field is divided into two sections: southern - Nakhchivan and Sust, located 4.5 km north-west of it. The physical and mechanical properties of both sections are close to each other. Losses are allowed during field development due to the fact that salt layers alternate with clay layers. The constantly growing demand for salt has predetermined the need to develop more advanced and progressive production methods based on the mechanization of technological processes, the use of new technologies and world experience. Depending on the formation of salt deposits, different methods of salt extraction are used in world practice. The main method of production of table salt in the world should be its extraction in the form of a solution and evaporation in the sun. The share of each of these methods is about 35%, and about 30% of the salt is extracted from an underground mine. The productive layer of the Nakhchivan rock salt deposit is 93-95% halite and is of high quality. The excess content of clay minerals in the field forces them to be used only in animal husbandry. Frosts drilled in the Nakhchivan rock salt deposit can be widely used in the treatment of liver diseases. The mountain has 130 million tons of natural salt reserves that are effective in treating respiratory ailments. Since the ice is horizontal, patients adapt to the underground part. To open new production facilities and treatment facilities in Duzdag, it is necessary to continue the installation of equipment that meets modern standards, the introduction of mines into a fully automated, controlled technological regime, equipped with a modern ventilation system.
