“…Metallurgical analysis methods such as microstructural investigations and fracture analysis are also found in the literature. Lastly, changes in the mechanical properties, such as UTS and elongation to fracture of the considered alloy before and after flux treatment, are also in use [34,58,[67][68][69][70].…”

“…Regarding the type of refining flux, Ghanaatian and Raiszadeh [67] investigated the efficiency of bifilm removal from an aluminum melt using a 50 wt % KCl-50 wt % MgCl 2 flux and applying stirring with a graphite rotor. By examining the RPT samples, they found that fluxing had a significant effect on bifilm removal and attributed the effect to a physical attachment of the oxides to the flux.…”

Aluminum recycling is a promising solution to environmental and economic issues. Secondary aluminum production will rise in the near future; however, the process is not without challenges. Some of the major concerns during remelting of aluminum are the metal losses due to the oxidation of the molten metal and the removal of impurities from the metal bath. The current study summarizes the latest progress in the use of solid salt fluxes for secondary aluminum production and the treatment of molten metal. The chemistry of solid fluxes has been reviewed, with a correlation to their main chemical and physical characteristics, such as density, fluidity, wettability, and reactivity. An overview of the main types of solid fluxes is also provided, with a particular focus on their functions and applications. The efficiency of solid fluxes relies on several factors, including but not limited to the fluxes’ chemical composition and physical properties, flux amount, processing temperature, and flux morphology. The effect of salt fluxes in delivering satisfactory metal cleanliness and sufficient metal recovery has been summarized according to the main flux’s properties.
