“…The stable phase equilibrium of the quaternary system was studied via the isothermal phase equilibrium method. 30 Several sets of phase equilibrium SL mixtures were prepared starting from ternary cosaturated points by adding third salt. The solid and liquid amounts of each SL mixture were predesigned to keep the volume ratio from 1/6 to 1/10 when the SL phase equilibrium (SLE) was achieved.…”

The solid−liquid phase equilibria of the Li + , Na + , Ca 2+ //Cl − −H 2 O quaternary system at 298.15 and 323.15 K are studied via the isothermal solubility phase equilibrium method. The solubility data and liquid properties of density and pH are obtained. The phase diagrams of the quaternary systems, including the water free diagram, the water diagram, and the dry salt diagram, are plotted to show the phase regions, water content, and salting-in effect. NaCl occupies the largest phase region at both 298.15 and 323.15 K. One double salt LiCl•CaCl 2 •5H 2 O occurs at 298.15 K and builds up two invariant points; one incommensurate invariant point saturated by (NaCl, LiCl•H 2 O, LiCl•CaCl 2 •5H 2 O) and one commensurate invariant point saturated by (NaCl, CaCl 2), but at 323.15 K, no double salt forms. The salting-in effect that happened in ternary systems still occurs in the quaternary Li + , Na + , Ca 2+ // Cl − −H 2 O system at both temperatures. NaCl saturated concentration increases with LiCl and CaCl 2 contents and results in a very high total salt content at commensurate invariant points, e.g., they are 56.92 and 60.62% at 298.15 and 323.15 K, respectively.

“…Wet solid samples are used for chemical analysis and identify the solid species by X-ray powder diffraction (XRD) and liquid samples are used for chemical analysis and the determination of density and pH. The details of the sampling procedure have been described in previous articles in our laboratory. , A brief summary is as follows: Wet solid sample: discharging the solid–liquid mixture from the bottom port of the SLE tank; separating solid and liquid phase rapidly by isothermal filtration; and drying the wet solid sample by filter paper. Liquid sample: stirring is stopped and the solid–liquid mixture is settled in the SLE tank until the liquid phase becomes completely clear; taking the liquid sample through the top port. …”

Brine deposited in Chaerhan salt lake belongs to the chloride type and can be simplified into the hexnary system Li+, Na+, K+, Mg2+, Ca2+, Cl––H2O. The known solubility data indicate that significant salting-in effects exist in its subsystems of KCl–LiCl–H2O and KCl–CaCl2–H2O, which inevitably affect the properties and solubility behavior of actual brine. In this work, the solubility behavior study and phase diagram determination are extended to the quaternary system of Li+, K+, and Ca2+∥Cl––H2O. The phase equilibrium data at 298.15 and 273.15 K are reported, and five solid species, including two double salts KCl·CaCl2 and LiCl·CaCl2·5H2O, are found. The salting-in effect is still exhibited in the Li+, K+, and Ca2+∥Cl––H2O system and results in a very high total salt content at invariant points; e.g., they are 59.08 and 46.93% at 298.15 and 273.15 K, respectively.
