Bauxite Processing Residue: A Critical Review of Its Formation .Feb 2, 2011 . Abstract. Bauxite is processed in alumina refineries by the Bayer process in which Al-containing minerals are dissolved in hot NaOH. . After mining, the bauxite is crushed and then processed at alumina refineries where the material is purified to produce Al oxide (alumina), the precursor to aluminum metal.bauxite ore how is it crushed,Bauxite mining - Norsk HydroHow do we get bauxite from the mines? Steps of the process: Mining - Transportation - Washing and crushing - Splits in two. Bauxite is usually covered by an overburden of several meters of rock and clay, which must be removed before the bauxite can be recovered. Then, the bauxite is transported to crushing or washing.A process for enhanced removal of iron from bauxite oresA process to remove iron from bauxite ore is described in which the ore is first finely crushed, calcined, and contacted with a reducing gas to convert iron present as very weakly magnetic goethite or hematite to magnetite or elemental iron.
