In terms of industrial scale application, various refineries have been supplying bauxite residue to cement industries without this necessarily being cited in the open literature (Mukesh, 2011, Sorin, 2011) or appearing only recently (Panov and Klimentenok, 2011). In the latter case where more information is disclosed, it is …
Microbial inoculation with appropriate inorganic–organic amendments is a promising strategy for ecological rehabilitation at bauxite residue disposal areas. Nevertheless, research on screening suitable plant growth-promoting bacteria with tolerance to highly sodic-alkalinity is very limited in the literature. In this study, novel plant growth-promoting …
Bauxite is a sedimentary rock mineral that is the primary source of aluminum. It is formed through the weathering of aluminum-rich rocks in tropical and subtropical regions. The name bauxite is derived from the French village of Les Baux, where it was first discovered in 1821 by geologist Pierre Berthier. Bauxite is typically found in layers …
Bauxite residue, well known as red mud, a by-product of alumina industries, bauxite is used as a chief ore. Nearly 95% of the alumina is produced from Bayer's process, and only the remaining 5% is from sintering or combined process [1, 2].Per every 1 ton of aluminum, around 1–1.5 tons of red mud is generated by consuming 2–3 tons of …

Reactivity of various oxides present in bauxite vary with process conditions, hence, one way of enriching bauxite with Al 2 O 3 is by sequential separation of Fe 2 O 3 and TiO 2 and then further second stage chlorination of enriched bauxite. Alpha alumina form is not preferred for carbochlorination as it is a stable form [].Hence, the process …
