Leaching of Bauxite Residue with Mineral Acids
Aiming at the industrial scale development of a Scandium (Sc)-selective leaching process 14 of Bauxite Residue (BR), a sufficiently numerous set of process design aspects has been 15 investigated, by appropriate exploitation of available experimental data. The interpretation of 16 experimental data for Sc leaching yield, with sulfuric acid as the leaching solvent, has shown 17 significant impac...

متن کاملPredictive hydrogeochemical modelling of bauxite residue sand in field conditions.
The suitability of residue sand (the coarse fraction remaining from Bayer's process of bauxite refining) for constructing the surface cover of closed bauxite residue storage areas was investigated. Specifically, its properties as a medium for plant growth are of interest to ensure residue sand can support a sustainable ecosystem following site closure. The geochemical evolution of the residue s...
متن کاملAmending Bauxite Residue Sands with Residue Fines to Enhance Growth Potential
Long term success of rehabilitation on bauxite-processed residue storage areas is dependant on establishing a capping stratum which will satisfy water use and nutrient cycling requirements of the intended plant community. Bauxite residue sand is the primary growth media for rehabilitating residue disposal areas (RDAs) in Western Australia however; the sustainability of the vegetation cover can ...
متن کاملA Mineralogical Assessment on Residues after Acidic Leaching of Bauxite Residue (Red Mud) for Titanium Recovery
Due to its alkalinity, red mud produced by the Bayer process may affect both the environment and human health. For this reason, its further utilization instead of disposal is of great importance. Numerous methods have already been studied for hydrometallurgical treatment of red mud, especially for the recovery of various metallic components such as iron, aluminum, titanium or rare earth element...
