Mapping Bauxite Mining Residues Using Remote Sensing Techniques [PDF]

International Conference on Raw Materials and Circular Economy, 2022
Bauxite residuals from abandoned mining sites are both an environmental challenge and a possible source of secondary raw materials. Processing of multispectral and hyperspectral images with the best available techniques can help to produce multiscale spatial maps of elements inside and around the mining sites.

Modification of bauxite residue with oxalic acid for improved performance in intumescent coatings [PDF]

, 2021
Valorization of bauxite residue (BR) enhances the dynamics of its application in intumescent coating for fire retarding systems. This BR, an alumina production waste could contain up to 45% ferrous oxide along with residual aluminous minerals.
