Initially, bauxite is extracted by mining. Then, it is converted to alumina via the Bayer process. According to the worldwide average, 2.3 tons of bauxite is necessary to produce 1 ton of alumina. Primary aluminum is produced via the Hall–Héroult process, a process of electrolytic reduction in a molten bath of natural and synthetic cryolite. Two tons of alumina is necessary to produce 1 ton

Bauxite consumption per ton of alumina has increased in recent years (from around 2.7 tons in 2005) due to declining quality of bauxite resources and now three tons of bauxite are required to produce one ton of alumina and two tons of alumina are required for the production of one ton of primary aluminum metal. However, the energy efficiency of the Bayer process has improved over that period

During this process, the finely ground bauxite ore is digested under pressure in a strong caustic (sodium hydroxide) solution at temperatures ranging from 100 to 260 °C. The resulting sodium aluminate-rich liquor is separated by physical means, such as settling and filtration, from the insoluble residue, known as bauxite residue. Typically, depending on the type of bauxite used, 1 t of

Also of importance is the relative amount of the three phases: gibbsite, boehmite, and diaspore as their dissolution characteristics in the Bayer process are quite different. By far, gibbsite is the cheapest to process. In 1873, bauxite mining began in Villeveyrac in France. Since then, bauxite mining has grown to a huge scale.
