Beneficiation of bauxite ores

Studies conducted at Hindalco with typical bauxite ore from Central Indian deposits have revelated that such ores are amenable to simple beneficiation process to reduce the reactive silica content to some extent. More research must be conducted to improve the liberation and separation of gangue mineral from the alumina-bearing …

Biomineralization and Biobeneficiation of Bauxite

Role of indigenous microbes in the formation and conversion of bauxite minerals is illustrated. Many types of microorganisms such as fungi, heterotrophic and autotrophic bacteria and yeasts inhabit bauxite ore deposits bringing about biogenesis and biomineraliztion. Organisms capable of iron oxidation and reduction and solubilising …
