How aluminium is produced
The next stage in the production chain is the processing of bauxite into alumina, or aluminium oxide - Al 2 O 3, - a white powder. The most common process for making alumina from bauxite is the Bayer process, which was first discovered over 100 years ago but is still in wide use today. About 90% of alumina refineries in the world use the Bayer ...

The reaction of fluorspar (CaF2) and sulphuric acid yields hydrofluoric acid. CaF2 + H2SO4 → CaSO4 + 2HF. Treatment of chloroform, obtained by reacting methanol and chlorine, with the hydrofluoric acid yields monochlorodifluoromethane, also used as a refrigerant, which is a gas boiling at −40.8°C. CHCl3 + 2HF → CHClF2 + 2HCl.
