Best answer Baeyer's Process The extraction of aluminium from bauxite involves three steps: • The purification of bauxite using Bayer's process. • The electrolytic reduction of anhydrous Al2O3 by Hall and Herault's process. • The last step is the purification of impure aluminium by Hoope's process

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.

(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.

Answer Finely powdered bauxite (Al2 O3 )is heated with coke and N2 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. Al2 O3 ⋅2H2 O+N2 +3C2000K 2AlN+3CO↑+2H2 O SiO2 +2C→Si↑+2CO↑ AlN+3H2 O→Al(OH)3 ↓+NH3
