Recycling of black dross containing rare earths originating from
The processing of black dross arising from the recycling of aluminium is well-established (Graziano et al., 1996, Unger and Beckmann, 1992, Rombach, 1998). By crushing and screening, metallic and non-metallic fractions are separated. The non-metallic fraction is treated by water leach with subsequent crystallisation of NaCl and KCl.

What Is Dross In Welding? [Updated On- 2024]
Dross is a residue that is left on the surface of molten metal. It is generally composed of oxides, and can form on the surface of both metals and alloys. Dross can be removed from the surface of molten metal through skimming or other methods. Slag, on the other hand, is the material that separates from molten metal.
