Aluminum Mineral Processing and Metallurgy: Iron-Rich Bauxite

Mar 27, 2018  Bauxite is the main source for alumina production. With the rapid development of iron and steel industry and aluminum industry, high-quality iron ore and bauxite resources become increasingly tense. However, a lot of iron-rich bauxite and Bayer red mud resources have not been timely and effectively recycled, resulting in serious problems of environmental pollution and wastage of resources.

Bauxite Mining and Aluminum Processing - Bruker

Bauxite is the primary source for aluminum (Al). Ores in this group include aluminum hydroxides, gibbsite, boehmite and diaspore. It is not just the concentration of aluminum that is important for bauxite mining, but also the identification of penalty elements such as iron oxide that may also make overall compositional analysis more challenging.

Advances in Beneficiation of Low-Grade Bauxite SpringerLink

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.
