Abstract:

A major sustainable challenge faced by the aluminum industry is to provide solutions regarding the reuse of its major hazardous residues (red mud and spent pot lining). This investigation addressed the characterization of the two residues as a preliminary step in the search for potential geopolymeric applications. The techniques utilized were X-ray diffraction, XRD, and Fourier Transform Infrared Spectroscopy, FTIR, for the red mud (RM) and X-ray diffraction and X-ray florescence, XRF, for the spent pot lining. The presence of traces of crystalline and amorphous phases in the RM was detected by FTIR. These phases may enhance the geopolymeric properties and their type and amount depend on the bauxite ore characteristics. The SPL characterization indicated the presence of aluminum and also of other metallic elements that are deleterious for geopolymeric applications.
