Abstract: Aluminum 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.

In this article, the results of an investigation of granular and compact aluminum drosses are reported. The bulk density of granular drosses was determined according to DIN 52110-B, while DIN 52102-RE-VA was applied to compact drosses. The salt contents of the drosses were measured by applying the leaching test DIN 38414-S4; the metal contents by the …
