Different from smelting brown corundum, smelting brown corundum mainly reduces SiO2 and Fe2O3 in bauxite to Si and Fe. However, the sub white corundum should not only reduce SiO2 and Fe2O3 to Si and Fe, but also reduce other oxides other than Al2O3, especially TiO2 in bauxite to Ti as much as possible.

1. What is Grinding process? In the grinding process, the cutting tool used is of emery or corundum. Emery and corundum are naturally found abrasives and are impure forms of Aluminium oxide Al 2 O 3. A grinding wheel consists of tiny abrasive particles embedded in a matrix called the 'bond'. An abrasive is an extremely hard material.

The first rule deals with the conservation of mass. The total flow of the material into the process plant equals the total flow out. The second rule relates to the quality or grade of the concentrate product. In practice, it is impossible to produce a concentrate consisting of only one mineral. The third rule is a corollary of the second.
