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

Radiological assessment of the bauxite residue valorization chain [PDF]
Journal of Radioanalytical and Nuclear Chemistry, 2019 The behavior of radionuclides in the bauxite residue valorization chain has been analyzed, and accumulation ratios have been measured for secondary residues produced after recovery of valuable metals. Key analysis outcomes are valid specifically for the processes and raw materials in use at the Aluminium of Greece plant and are as follows: the ...
