This study investigates the production of magnesium chloride from magnesium-containing brines by the isothermal method at 25 °C within the quaternary system 2Na⁺, Mg²⁺ // SO₄²⁻, 2Cl⁻ – H₂O. Natural brines of the Alat and Kagan lakes (Bukhara region) were analyzed as potential raw materials. The solubility diagram of the reciprocal system was constructed, and the exchange reaction 2NaCl + MgSO₄ ⇄ Na₂SO₄ + MgCl₂ was confirmed. Crystallization fields of the main solid phases were determined, revealing the high solubility of magnesium chloride compared to other components. Based on phase equilibrium analysis, a technological approach for stepwise separation of sodium and magnesium salts is proposed, providing a scientific basis for organizing magnesium chloride production from local saline resources.
