    28.09.2020· Beneficiation and mineral processing of bauxite and feldspar Bauxite is a sedimentary rock that is rich in alumina, the base for making aluminum. It is generally easy to mine because it is found near the surface of terrain. However, the process for separating the alumina from the other base elements in bauxite can be environmentally unfriendly.

  • Bauxite Beneficiation & Flotation | Silica & Iron

    Bauxite is a sedimentary rock, and consists mostly of the aluminium minerals gibbsite (Al (OH)3), boehmite (γ-AlO (OH)) and diaspore (α-AlO (OH)), and is usually mixed with the two iron oxides goethite and hematite, the aluminium clay mineral kaolinite and small amounts of anatase (TiO2) and/or ilmenite (FeTiO3).
