bauxite benefitiation

    • Beneficiation of bauxite

    The silica present in the bauxite tends to be concen-trated in the finer grained fractions, and this charac-teristic makes bauxite amenable to beneficiation by screening techniques. Pearson' has reported that in a bauxite of average composition of 1.58% silica, the minus 100 mesh fraction analysed a silica content as high as 10.30%.

    Abstract. Bauxite is the major alumina (Al 2 O 3) bearing ore used in the aluminum manufacturing industries.The bauxite containing less than 50% Al 2 O 3 is called low-grade bauxite ore which is commonly used for the alumina-based abrasives and refractories productions. The alumina-silica and alumina-ferrite complexes are the foremost impurities present in the low-grade bauxite.
