In terms of production volume, aluminium is the leading metal in nonferrous metallurgy. In particular, the recycling of aluminiumcontaining residues has strongly increased in recent years and will continue to gain importance in the future. Due to the high affinity of aluminium to oxygen, the oxidation of the molten bath is unavoidable, which leads to the formation of dross on the surface ...
