Bauxite was first discovered in the area around 1820 and from 1850 industrial methods to extract extract aluminium from bauxite became available. Several mines were in operation around the village of Les BauxdeProvence and until 1939, France was the world''s largest single producer of bauxite.
In the Bayer Process, the bauxite is washed in a hot solution of sodium hydroxide, which leaches aluminum from the bauxite. The aluminum is precipitated out of solution in the form of aluminum hydroxide, Al(OH) 3. The aluminum hydroxide is then calcined to form alumina, Al 2 O 3. Aluminum is smelted from the alumina using the HallHeroult Process.
