Iron Separation from Bauxite Through Smelting-Reduction Process
2017.2.12 The principal ore of aluminum extraction today is bauxite , although aluminum is found in other types of ores . Aluminium is produced in three stages, first it is mined, then made into alumina (Al 2 O 3 ) through the Bayer process , and finally the alumina is reduced to aluminium by the electrochemical process Hall-Hèroult [ 1 ].

THE ALUMINIUM STORY BAUXITE TO ALUMINA: THE BAYER PROCESS
The ultimate product of calcination is the most stable phase of alumina, corundum or -alumina. This is, however, not desirable for smelting, because -alumina is slow to dissolve in the bath (refer to Section 24). For the formation of Smelting Grade Alumina (SGA), calcination is carried out at around 950°C.
