Abstract
The disposal of aluminum bearing dust can cause heat and gases, as well as the potential generation of leachate from landfills. In this research, we suggested a two-step process - leaching and precipitation - for recovering gibbsite from secondary aluminum production dust. First, a sodium aluminate solution, containing about 20 g/L of aluminum, was prepared using 1 M of sodium hydroxide leaching. Precipitation of the gibbsite was then conducted for 30 min after a pH adjustment. As the results indicate, the overall aluminum recovery rate was about 87% by weight after leaching and precipitation, and the major component of the precipitate was Al(OH)3 based on an X-ray diffraction(XRD) analysis.
