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.

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,

Induced shear in reinforced concrete beams with synthetic aggregate
Revista IBRACON de Estruturas e Materiais, 2023 The increasing aluminum production demands larger volumes of bauxite residue (BR) to be stored in the Amazon region. There are millions of tons of waste without reuse but with high potential for use in civil construction as artifacts or components for ...
