“…Iodine is utilized globally in the food and pharmaceutical sectors, as well as in medicine, veterinary medicine, the manufacture of mineral fertilizers, and as a catalyst in the chemical industry [1]. It is also employed in producing ultrapure materials, special glass, fuel, and synthetic rubber, which are used in industrial and agricultural machinery [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21].…”

Studies using physico-chemical methods have been conducted to evaluate the oxidative characteristics of various reagents for the technological extraction of iodine from groundwater and sufficient data have been obtained. According to the research results, iodine is predominantly present in the form of molecular iodine (85.6%), iodide ions (3.2%), iodate (9.1%) and iodine chloride (2.1%) were detected. Preserving all forms of iodine in solution at the same time is possible only in an alkaline environment, where the oxidizing properties of iodates are sharply reduced. This information is important for choosing a method for purifying iodine paste using various physical and chemical methods. From experiments in research, the beginning of the release of elemental iodine was noted at a voltage above 0.250 V and a pH of 5-3 or less. In this case, the solution usually becomes dark red with a reddish or brownish tint, which indicates the formation of complex compounds of iodine with other ions in the solution.

In this article, the chemical and mineralogical composition of the local quartz sands of Surkhandarya region was initially determined by the method of X-ray phase analysis. The sand was then washed and dried several times in distilled water for enrichment. The resulting clean sand was crushed, sifted and returned with magnesium at temperatures of 600–1800°C at intervals of 2–10 hours, technical Silicon (93%-94%) was obtained. Silicon oxide and magnesium metal for magniothermal extraction 2:1, 1:1, 1:2, 1:3, 1:4, 1:7 the goods were taken in proportions. It was washed three to four times in distilled water, hydrochloric acid, alkali to extract Silicon from the composition of the resulting reaction mixtures. The purity of the extracted Silicon was studied using X-ray phase and element Analysis. The study found that the optimum temperature for reaction of silicon oxide with magnesium was 800°C temperature, reaction duration was 6 hours, with a molar ratio of silicon oxide and magnesium of 1:2, the reaction yield showed the highest result of 98,8%.
