Get Pricealuminum industry produces approximately 3.2 million tons of dross annually from domestic aluminum smelting. Most of the interest has been on the recovery of the aluminum content of the dross, as white dross can reach as high as 80wt%. In order to recover the metallic aluminum, dross is heating in a rotating furnace with a salt flux introduced.
Get PriceAluminum dross, a byproduct of the aluminum melting process, is a mixture of aluminum, its oxides, the oxides of alloying elements and less frequently halogenides, carbides and nitrides. Dross has some good benefits, especially considering tension strength and depending on further conditioning steps can be very useful further on.
