Production Process Of Brown Corundu

After crushing and grinding, the small particles of bauxite are placed in calciners. Calcination is the process of heating the bauxite to a high temperature (around 1300°C) to remove any impurities and transform it into corundum. During this process, the bauxite undergoes a phase change from trihydrate to monohydrate, then to corundum. 4.
