Beneficiation of Low-Grade Bauxite: A Case Study of
2021-7-2 Thus, any beneficiation process which can reduce silica (mainly in reactive form such as kaolinite) and iron content in bauxite and laterite, are important from processing point of view. The studies have been done by organizations/industry on beneficiation on low grade bauxite mainly for removal of impurities such as iron oxide, silica [ 15 ].

Advances in Beneficiation of Low-Grade Bauxite
2019-2-16 Bauxite containing less than 50% Al 2 O 3 is called low-grade bauxite ore, which is generally used for the production of aluminum appliances such as abrasives, ceramics, and refractories . The presence of impurities, including silica, iron oxides, and calcium contribute to the bauxite being classified as a low-grade ore.

Characterization and Beneficiation Studies of a Low Grade
2014-8-19 At present, the beneficiation of low-grade ores has not been given much importance except in some sources for the removal of silica by size reduction through manual or mechanized breaking. The literature contains a number of references [ 4 7] to minimize the reactive silica and iron content particularly from boehmitic or diasporic bauxite ore.
