Aluminum smelting and aluminum fabrication companies, especially aluminum alloy manufacturing companies will add a variety of solvents and refining agent during the melting process in order to obtain high-quality and high-purity aluminum ingot or aluminum alloy. After solid solvent and refining agent melt, they will react with impurities in the melting substance and produce a certain amount of dross, generally known as the aluminum dross. Aluminum dross contains large amounts of aluminum. Appropriate solutions to recycle aluminum from aluminum dross should be adopted.
 
Aluminium dross represents a residue from primary and secondary aluminium production. Drosses are classified according to their metal content into white and black dross. White dross is of higher metal aluminium content and it is produced from primary and secondary aluminium smelters, whereas black dross has a lower metal content and is generated during aluminium recycling(secondary industry sector). White dross may contain from 15 to 70% recoverable metallic aluminium and it comprises a fine powder from skimming the molten aluminium. Black dross typically contains a mixture of aluminium oxides and slag, with recoverable aluminium content ranging between 12 to 18%, and much higher salt content(typically higher than 40%) than the white dross. The non-metallic residues generated from dross smelting operations is often termed "salt cake" and contains 3 to 5% residual metallic aluminium.
 
Aluminum dross processing (recycling) device in our company can not only effectively extract aluminum from aluminum dross, but also make outstanding contributions to environment protection by fully achieving the regeneration of waste resources. It also reflects our company’s goal---to make waste harmless, reduce waste and turn waste into useful resources. Based on unique design and advanced technology, this device has a high recovery rate of aluminum as high as 85-95%.
