The first commercial extraction of alumina (Al 2 O 3) from bauxite has been attributed to Henri SainteClaire Deville in about 1854.. Soon after this, in 1888, Karl Joseph Bayer described what is now known as the Bayer Process, which led to a dramatic reduction in the cost of aluminum metal.
The first step in producing aluminium is mining its ore – occurs mainly in tropical and subtropical areas, like Africa, the West Indies, South America and Australia – there are some small deposits located in Europe. Australia is the largest producer of bauxite, with five mines supplying around 23 per cent of global production.
The bauxite residue sinks to the bottom of the settling tanks, then is transferred to the washing tanks, where it undergoes a series of washing stages to recover the caustic soda (which is reused in the digestion process). Further separation of the pregnant liquor from the bauxite residue is performed utilising a series of security filters.
