Geotechnical characterization of bauxite residue (red mud) [PDF]
, 2015 Bauxite residue is the iron-oxide rich mine waste from the processing of bauxite ore for the extraction of alumina through the Bayer process. The Bayer process uses caustic soda, high pressure, and high temperature to leach alumina from ferruginous ...

Recycling and potential utilization of red mud (Bauxite Residue) for construction industry applications [PDF]
, 2022 Red mud (RM, a Bauxite Residue) is the huge waste materials generated during the alumina production followed by the Bayer Process, which processed about 1.25 – 1.5 ton from per tons of alumina production. The disposal of this waste materials is a serious

Microbially-driven strategies for bioremediation of bauxite residue [PDF]
Journal of Hazardous Materials, 2015 Globally, 3 Gt of bauxite residue is currently in storage, with an additional 120 Mt generated every year. Bauxite residue is an alkaline, saline, sodic, massive, and fine grained material with little organic carbon or plant nutrients. To date, remediation of bauxite residue has focused on the use of chemical and physical amendments to address high pH,

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 ...

Influence of natural regeneration on fractal features of residue microaggregates in bauxite residue disposal areas [PDF]
, 2017 Bauxite residue is often physically degraded, which limits vegetation establishment on the disposal areas. Microaggregate stability is an important physical property due to its significant effect on erosion and surface runoff, however this is rarely ...

High Temperature Reduction of Bauxite Residue
Materials Proceedings, 2022 The present study focused on investigating the high-temperature reduction of bauxite residue, also known as red mud. A series of reduction experiments on red mud was performed to investigate the influences of temperature (1400, 1450, and 1500 °C ...

Carbothermic Reduction of Bauxite Residue.
Shigen-to-Sozai, 1999 A recovery method of iron component as metallic phase from bauxite residue (red mud) discharged from Bayer process was examined. Tablets prepared with fine mixtures of red mud and carbonaceous materials were heated up to various temperatures to reduce iron oxides in the red mud.
