Hint: We know that Serpeck's process is used for purification of Bauxite. Bauxite contains impurities of silica in excess amount, which needs to be removed. The bauxite powder is mixed with carbon and heated under high temperature (above 1800^circ C) and a current of nitrogen is passed. Through this process aluminium nitride is obtained ...

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. We cannot compare these two processes as they are used for two different impurities.

Recently I was taught how aluminium is commercially extracted. The ore is first concentrated by leaching either by Bayer's process for red bauxite (impurity: ce{Fe2O3}) or by Serpeck's process for white bauxite (impurity: ce{SiO2}). Then alumina is reduced electrolytically via HallHéroult's process directly to 99% pure aluminium.

The metal obtained in the HallHéroult process is about 99% pure, and for most purposes it is taken as pure metal. However, further purification of aluminium can be carried out by the Hoopes process. This is an electrolytic process. Serpeck's Process Bauxite containing high percentage of silica can be purified by Serpeck's process.

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↑
