The Efficient Use of Sulfuric Acid in Bauxite Residue Leaching
Materials Proceedings, 2023 Bauxite residue (BR), an alkaline industrial waste, is a major byproduct of the alumina production process known as the Bayer process. The Bayer process generates a byproduct known as bauxite residue (red mud). This residue was leached with sulfuric acid

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.
