Metallic aluminum in aluminum dross is recovered in Japan generally by physical separation, using the so-called Metal Reclamate Machine (MRM). A large amount of the residue containing oxides, metallic aluminum, nitrides and salts is unavoidably generated as a by-product of the MRM process. Since the metallic aluminum is much more viscous than the relatively brittle oxides and nitrides, it .

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.

Aluminium recycling is the process by which scrap aluminium can be reused in products after its initial production. The process involves simply re-melting the metal, which is far less expensive and energy-intensive than creating new aluminium through the electrolysis of aluminium oxide (Al 2 O 3), which must first be mined from bauxite ore and then refined using the Bayer process.
