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.

(iii) Lead metal is obtained by the process of smelting which uses carbon as the reducing agent. So, the statement is true. (iv) Serpeck method is used for the purification of white bauxite and not red bauxite. So, the statement is false. Based on the above observations we can conclude that the correct order is TFTF.

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.

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.

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.
