The study focuses on the reactions of Ca²⁺ and Mg²⁺ with bicarbonate ions (NaHCO₃ and (NH₄)₂HCO₃), leading to the formation of carbonate-based precipitates. Experimental conditions such as temperature, pH, and ionic strength are analyzed to optimize the process. Mathematical modeling is applied to simulate the behavior of the system in aqueous media. The findings contribute to enhancing the efficiency of mineral processing, softening of hard water, and environmentally friendly methods for utilizing dolomite resources. Keywords: Dolomite, calcium, magnesium, selective separation, bicarbonate ions, aqueous precipitation.
