Advances in Beneficiation of Low-Grade Bauxite |

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.

Today, nearly all commercial production of alumina is obtained from standard Bayer process using bauxite ores as a raw material. One of the most important criteria for metallurgical-grade bauxites that can be directly fed to the Bayer process is the total silica content of bauxite. Because, reactive silica which tends to dissolve during bauxite leaching causes excessive caustic soda ...

Beneficiation of High Silica Bauxite Ores of India an ...

Abstract. Many bauxite reserves in India have Al 2 O 3 /SiO 2 ratio of 4 to 6 and hence pose difficulties in production of alumina through the Bayer process. The extraction of alumina from bauxite in low temperature digestion circuit frequently involves a desilication step in which kaolinite dissolves and reprecipitates as sodalite, a caustic insoluble sodium alumino silicate.

Bauxite washing for the removal of clay | SpringerLink

Clay impurities associated with bauxite negatively affect the Bayer process for alumina production. These impurities should be removed as far as possible by a beneficiation technique before the ore is used as feed for the Bayer process. In this current investigation, bauxite washing was conducted in the laboratory. Bauxite washing is a physical process that causes the disintegration and ...
