  • Beneficiation of diasporic-bauxite ore by selective

    2008-8-1 · 1.. 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., 2002).DRY BENEFICIATION OF BAUXITE MINERALS USING A ,2021-5-8 · Bauxite deposits are spread worldwide, mostly occurring in tropical or subtropical regions [8]. Bauxite mining of both metallurgical and non-metallurgical grade ores is analogous to the mining of other industrial minerals. Normally, the beneficiation or treatment of bauxite is limited to crushing, sieving, washing, and drying of the crude ore [3].
