purification process of bauxite ore

2019-4-7 · This process is used for the purification of bauxite ore containing silica (SiO2) as the main impurity. The powdered ore is mixed with coke and the mixture is heated at about 1800°C in the presence of Nitrogen gas, when aluminium nitride is formed. Al2O3. 2H2O + 3C + N2 → 2AI N + 3CO+ 2H2O
