The Bayer Process was invented and patented in 1887 by Austrian scientist Karl Josef Bayer. Two to three tonnes of bauxite are required to produce one tonne of alumina. 90% of the global alumina supply of around 90 million tonnes is used in aluminium production. Alumina refineries tend to be loed close to bauxite mines and/or ports for efficient transport of raw materials and of the final ...

The Bayer Process starts off with the bauxite being washed in a hot solution of sodium hydroxide, which removes the aluminum from the rock. Once this happens, the aluminum is removed from the solution in the form of aluminum hydroxide. This is then calcined to form alumina, which is later used in refining companies for various products. It can be used in cement, chemicals, cosmetics, soda cans ...
