· Abstract. The main objective of bauxite beneficiation is to lower the concentration of reactive silica, in the form of kaolinitic clay, and also to increase the alumina content. Additionally, reduction in iron content, particularly in the form of goethite, and reduction of organic carbon can also increase the value of the bauxite product.

· Bauxite is found in many parts of the world, but more particularly in tropical areas. Bauxite is of supergene origin commonly produced by weathering and leaching of silica from aluminum bearing rocks. Bauxite may occur in situ as a direct result of weathering or it may be transported and deposited in sedimentary formation. . Gibbsite

· In this process, bauxite residue is smelted at 1500 °C or higher in presence of a flux and a reductant to produce pig iron and slag. Alumina in the produced slag is mainly in the form of calcium aluminate that can be treated with Na 2 CO 3 solution. The leach residue generated from this process is known as gray mud.
