Investigation of Phase Equilibria and Polythermal Solubility in the MgCl₂–NaCl–H₂O System for the Extraction of Magnesium-Bearing Raw Materials from Natural Brines

Short summary

This study maps the phase equilibria and solubility in the MgCl₂–NaCl–H₂O system, identifying key crystallisation regions and phase-transition temperatures down to -35.6°C. The research demonstrates that increasing magnesium chloride concentration reduces sodium chloride solubility, a salting-out effect beneficial for magnesium enrichment.
