Why is salt added when melting aluminium? - Quora

Answer (1 of 2): When remelting aluminum scrap, the molten aluminum oxidizes quickly and forms a layer of dross [1] and floats on top of the melt. If the dross accumulation results in a quality problem with the casting, dross volume can be reduced by covering the melt with molten salt(s) [2]; sa
