IntroductionBauxite ores in China have characteristics of diasporic-type with high content of aluminum and silica, low content of iron and low Al 2 O 3 to SiO 2 mass ratio. In diasporic-bauxite ore processing, silicates are easily over-ground and the fine silicate slimes are harmful to direct and reverse flotation beneficiation of bauxite (Wei et al., 2001, Zhao et al.,Dry beneficiation of bauxite minerals for greater yields,Dry beneficiation of bauxite minerals for greater yields. The primary starting material for aluminum refining is bauxite. Since aluminum is a reactive element and does not occur naturally, aluminum-rich ore needs to be refined to produce alumina and aluminum, resulting in a significant generation of by-product residue.Reasons For Bauxite Beneficiation - Hatch Ltd,Due to the high grade of reactive silica in the Brazilian bauxite ores, the Brazilian mines have included a beneficiation plant to reduce the reactive silica prior to the refinery, by removing the finer fraction of the material, usually under 37 μm.
