| Outline of Final Research Achievements |
A new treatment process of aluminum dross residue containing oxides, metallic aluminum, nitrides and salts was proposed for sustainable society. Also the structural and chemical properties of aluminum dross residue from metal recovery process were investigated for new recycling process including proposed process. In which, the relationship between the composition and the grain size of the residue was investigated to develop an easier technique for upgrading aluminum dross residue. According to the results, the mean sizes of studied residues were 100 - 200 micro meter. The residues larger than about 200 micro meter had higher metallic aluminum content, whereas their aluminum nitride and chlorine contents were lower. It was confirmed that the metallic aluminum content of the residue could be easily increased by the proposed screening process.
