Mining and Refining Process. 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 located close to ...
Once the bauxite is loosened into manageable pieces it is generally loaded into trucks, railroad cars or conveyors and transported to crushing and washing plants or to stockpiles, before being shipped to alumina refineries, which are generally located close to bauxite mines. Unlike the base metal ores, bauxite does not require complex ...

Bauxite reserves are spread across the world. Large deposits include Australia, Brazil, Guinea and Jamaica. Around 85% of all Bauxite mined from the Earth is used to produce aluminium metal, which goes on to be used for a huge variety of uses. The remaining 15% goes towards chemical and refractory materials, along with making aluminium compounds.
Interestingly, production of bauxite is registered particularly in those regions that supply alumina plants with this ore. Bauxite ore has benefited in importance because aluminium-a very light but exceedingly functional metal, is made from it. It is a must for aircraft engineering. It is now also being increasingly used in day-to-day life.
production of alumina and aluminum metal globally. More than 85% of the bauxite mined globally is converted to alumina for the production of aluminium metal. An additional 10% goes to non-metal uses in various forms of specialty alumina, while the remainder is used for non-metallurgical bauxite applications (Sustainble Bauxite Mining.., 2018).
