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. Al 2O 3⋅2H 2O+N 2+3C 2000K 2AlN+3CO↑+2H 2O SiO 2+2C→Si↑+2CO↑
3 Answers Sorted by: 3 From this source Baeyer's process: This method is mainly applied when ferric oxide is present as chief impurity. Serpeck's process: This process is used when silica is present in considerable amount of bauxide ore. I couldn't find any information on the efficiency, but I suspect both are efficient in their own way.
