Aluminium dross recycling - Wikipedia

Aluminium recycling is where pure aluminium metal products (previously used in another form) are re-melted into aluminium ingots and then re-used to new aluminium products. While aluminium dross recycling is where the dross, a byproduct of the smelting process in the creation of aluminium from bauxite, can be mechanically recycled thus separating the residual aluminium metal from the ...

Dross - Wikipedia

Dross is a mass of solid impurities floating on a molten metal or dispersed in the metal, such as in wrought iron. It forms on the surface of low-melting-point metals such as tin, lead, zinc or aluminium or alloys by oxidation of the metal.For higher melting point metals such as steel, oxidized impurities melt and float making them easy to pour off.
