How is Bauxite purified by Serpeck's process? Medium Solution Verified by Toppr Finely powdered bauxite (Al 2O 3) is heated with coke and N 2 to 2000 K. Alumina forms aluminium nitride and silica is reduced to Si which is volatile. The hydrolysis of aluminium nitride gives aluminium hydroxide which on heating gives pure alumina.
