2020-7-15  However, the iron content in high-iron bauxite is the main reason that hinders efficient utilization. This is because iron in bauxite is a harmful element in the Bayer process. Iron can exist in bauxite as goethite (FeOOH), which has the same structural topology as diaspore (AlOOH) [7,8]. Therefore, iron-aluminum ions can be easily replaced with each other to form an iron-aluminum
