Aluminum oxide dross layer, which forms a layer on the top of molten metal, can be removed from the molten metal through drossing fluxes. Dross and metal (in liquid or solid form) are usually blended together in this layer of dross. When drossing fluxes react on aluminum oxide in slag or dross layer, metal can usually be separated and recovered.
