| titleOfInvention | Process for converting waste aluminum dross residue into useful products |
| abstract | The invention relates to a process for converting waste aluminum dross residue to valuable products. The process involves mixing the dross residue with sodium oxide or a precursor and heating the mixture to 800-1300 °C for a period of time long enough to form a solid material containing sodium aluminate, generally 10 minutes to 2 hours. The resulting aluminate-containing material is thus partially dissolved in an aqueous liquid, preferably an aqueous alkali, to form a solution and undissolved solids. The solution, which generally contains NaOH and Al(OH)3, is separated from the undissolved solids and used without further purification for a variety of uses, e.g. papermaking and water purification. The solution can also be added to the aluminate solution of the Bayer process to recover alumina values from the dross residue, in which case salt cake from the Bayer process can be used as the sodium oxide precursor and spent Bayer liquor can be used as the aqueous liquid. The process is made more thermally efficient if a dross containing AlN and/or metallic Al is employed, since these components oxidize exothermically during the process. |
