    In the bauxite refining process, the aluminum bearing minerals in bauxite are converted in a multiple step process to alumina (Al2O3). Alumina can be smelted to form metallic aluminum or it can be used as the source of many other products, including refractory materials used to line high temperature rotary kilns and metallurgical furnaces.
