Preliminary Characterization of Three Metallurgical Bauxite Residue Samples
Materials Proceedings, 2021 Bauxite Metallurgical Residue (BR) is a highly alkaline and very fine-grained by-product of the Bayer process for alumina production. Its huge global annual production has resulted in increasing accumulation of BR, causing deposition problems and serious

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 ...

Enhanced Aluminium Extraction from Gibbsitic Bauxite by Electroreduction in the Bayer Process
MetalsThe Bayer process is used to extract alumina from bauxite, resulting in the formation of a highly alkaline solid residue known as bauxite residue (BR). However, such residue contains insufficient iron (

Acta Zoologica, EarlyView.ABSTRACT The order Xenarthra presents unique morphophysiological adaptations related to its specialized ecological niches. This study investigates the functional morphology and comparative myology of the thoracic limb in Cyclopes didactylus (silky anteater) and Tamandua tetradactyla (southern tamandua) to elucidate how muscle arrangements support ...

Sustainable Indian alumina refineries: beneficiation and reuse of bauxite residue
, 2015 Alumina is produced by refining bauxite, which is stripped from open cut mines; aluminium, one of the world’s most important lightweight metals used in packaging, transportation and construction, is in turn produced by smelting alumina. About 259 million

Medical and Veterinary Entomology, EarlyView.Bauxite mining in the Amazon alters mosquito communities, favouring anthropophilic and generalist vectors while reducing species diversity and the variety of blood meal sources. Molecular analyses identified humans, tapirs and deer as the primary blood meal sources.
