Abstract: The aim of the study is to obtain magnesium hydroxide by complex, nitric acid processing of dolomite from the Dekhkanabad deposit. The results of the influence of technological parameters on the degree of decomposition of dolomite with 40, 50 and 57% nitric acid at 100 and 110% norm are given, the kinetic characteristics of the process, the composition of the liquid phase, the degree of transition of the dolomite components into the nitric acid solution, the rate of clarification and filtration of the nitric acid extract, the ammonization process are established of clarified nitric acid solutions on the composition of the liquid phase, the degree of transition of dolomite components into the solution, the rate of clarification and filtration of nitric acid extract, the process of ammonization of clarified nitric acid solutions on the composition of the liquid phase and the degree of magnesium precipitation, the rate of nitric acid on the decomposition of dolomite and pulp temperature on the filtration rate of magnesium hydroxide.

Keywords: Dolomite, Nitric Acid, Nitric Acid Extract, Ammoniation, Magnesium Hydroxide, Clarification Rate, Filtration, Ecology.
