When is Serpeck's process preferred over Bayer's process?

When is Serpeck's process preferred over Bayer'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.

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.
