Bauxite. La bauxite est une roche sédimentaire blanche, rouge ou grise, caractérisée par sa forte teneur en alumine Al 2 O 3 et en oxydes de fer. Cette roche constitue le principal minerai permettant la production d' aluminium et de gallium. Elle se forme par altération continentale en climat chaud et humide.
2020年6月16日 Three typical litho-types such as ‘saprolite,’ ‘bauxite’ and ‘laterite/lateritic ore’ from different levels of khondalite-hosted bauxite profile of Baphlimali plateau, Rayagada district, Odisha, Eastern India, have been studied. Mineralogical variations between different size fractions are interpreted for their optimum utilization. Mineralogy of

Une bauxite à haute teneur en alumine est un mélange colloïdal finement dispersé d’hydroxyde d’aluminium et de divers ratios. La bauxite élevée dans l’industrie réfractaire se réfère habituellement au minerai de bauxite avec la teneur plus élevée d’Al2O3 que 48% et au contenu inférieur de Fe2O3 après calcination.
