In the current study, the chemical reactions involved during the recycling process are investigated using thermodynamic calculations. It is found that the melting temperature, density, and MgO solubility of conventional refining fluxes composed of MgCl2-NaCl-KCl-CaF2 salts are very sensitive to the flux composition. According to chemical reaction calculations, the solubility of MgO in the refining flux is much lower than the MgO impurity level in molten Mg. Therefore, the refining of Mg alloy, and in particular the removal of MgO by submersing molten flux, seems to be mainly achieved by physical attachment rather than chemical reaction. As a result, it is suggested that the liquidus temperature and density of the molten flux are important physicochemical properties to be considered in the selection of a proper refining flux for a given Mg alloy. In addition, calculations show that expensive and reactive alloying elements such as Ca, Sr, and rare-earth elements can be easily consumed by the molten flux during the refining process, which limits current refining fluxes. All thermodynamic calculations were performed using the FactSage thermochemical software.
