Review Hazardous aluminum dross characterization and recycling
In primary aluminum melting process, salt flux may possess multiple functions (Gil, 2005): a) it promotes heat transfer to the metal; b) it protects metal against the atmosphere; c) it helps in mechanical distribution of oxides and metallic and non-metallic materials in the furnace; d) some of salt fluxes can chemically react with aluminum ...
