2017-12-4  In addition to the above processes, sintering process is also used for alumina production from bauxite. In this process, Na2CO3 is added to react with Al2O3 in bauxite at high temperatures i.e. 1000˚C and water-soluble NaAlO2 is formed. The NaAlO2 compound in the sinter is leached by water and Al(OH)3 is further precipitated from the solution
