The main component of bauxite is Al 2 O 3, containing a small amount of Fe 2 O 3, SiO 2, and other impurities. The main objective of bauxite beneficiation is to lower the concentration of reactive silica, and also to increase the alumina content. In addition, bauxite beneficiation can also be used for iron extraction or iron removal.Web
