The process is a single one .Earlier process for extraction of aluminium was complex and costly .A young scientist Charles Martin Hall tried lot and found a process for extraction of aluminium which was scientific and not costly.On the same time another scientist named Poul Herault also found a similar way for extraction of aluminium. Thereafter the method was known as Hall-herault process Shaheed Vh · 4 years, 3 months ago

@Shaheed Vh no- in hall's process, naoh is used to reduce bauxite to alumina.... whereas, the next process(which we call hall-harault's) is actually the herault's process.... Shubham Sharma · 4 years, 3 months ago

In hall herault process, first alumina is melted with cryollite and then the molten mixture is electrolyzed.It is a single process Tilak Patel · 4 years, 3 months ago
