Need of refining aluminium and Hoope vs HallHéroult processes

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.
