Recovery of Metals from Aluminum Dross and Saltcake

2013-12-24  approach has been to upgrade the metallic aluminum content of dross wastes prior to re-melting. This is typically done by mechanically pulverizing the dross down to a coarse powder and then screening it with a 10 to 20-mesh screen. The oversize fraction (the concentrate) typically contains 60% to 70% metallic aluminum and is remelted. The

An easier upgrading process of aluminum dross

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 ...
