Bauxite Crushing And Grinding Machines Bauxite is a sedimentary rock that is the primary ore source for aluminum. It is formed through the weathering of aluminum-rich rocks in tropical or subtropical climates. The main mineral in bauxite is gibbsite (Al(OH)3), but it may also contain boehmite and diaspore.

· 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.
