“…Initial work in the optimization of the LiCl-NaCl-KCl-RbCl-CsCl-MgCl 2 -CaCl 2 system is described in the work of Chartrand and Pelton [42]. A modified quasi-chemical model for short-range ordering is utilized for the liquid phase to determine the thermodynamic properties and phase equilibria of binary and ternary systems of those salts.…”

Achieving the goals of the U.S. Department of Energy (DOE) Sunshot initiative requires 1) higher operating temperatures for concentrating solar power (CSP) plants to increase theoretical efficiency, and 2) effective thermal energy storage (TES) strategies to ensure dispatchability. Current inorganic salt-based TES systems in large-scale CSP plants generally employ molten nitrate salts for energy storage, but nitrate salts are limited in application to lower temperatures-generally, below 600°C. These materials are sufficient for parabolic trough power plants, but they are inadequate for use at higher temperatures. At the higher operating temperatures achievable in solar power tower-type CSP plants, chloride salts are promising candidates for application as TES materials, owing to their thermal stability and generally lower cost compared to nitrate salts. In light of this, a recent study was conducted, which included a preliminary survey of chloride salts and binary eutectic systems that show promise as high temperature TES media. This study provided some basic information about the salts, including phase equilibria data and estimates of latent heat of fusion for

“…Figure 3 shows the dependence of potassium extraction on the salt mixture composition for a range of temperatures and salt/ore = 1:1 (mass ratio). The salt compositions selected for this study are obtained from the phase diagram 36 developed ( Figure 3 b). The different phases of salt mixtures including liquid and solid–liquid phases, depending on the composition and temperature, were analyzed in the current investigation.…”

Experimental Kinetic Analysis of Potassium Extraction from Ultrapotassic Syenite Using NaCl–CaCl₂ Salt Mixture

This kinetic experimental analysis reports on the application of a eutectic NaCl–CaCl 2 salt system for the extraction of potassium from ultrapotassic microsyenite. The reaction parameters, time, temperature, salt composition, and salt to ore ratio, were systematically analyzed. It was found that a salt mixture increases the potassium cation extraction in comparison with using either pure NaCl or pure CaCl 2 . It was also found that adding CaCl 2 into pure NaCl has a considerably stronger effect on increasing the potassium recovery than adding NaCl to pure CaCl 2 . The salt as a melting agent offers a reduction in the reaction temperature due to its lower melting temperature when compared to pure salts (NaCl or CaCl 2 ). Approximately 70% of K + in the deposit was extracted at 650 °C. Different characteristic methods have been used to understand the reaction mechanism of the salt mixture and ore, as well as to qualify and quantify the end product mineral phases.
