An easier upgrading process of aluminum dross residue by ...

2014-7-8  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
