Approximately 85% of the world’s bauxite production is metallurgical bauxite and the alumina is extracted from the bauxite in a refinery using a wet chemical caustic soda leach process known as the Bayer process The alumina is then converted to aluminium metal via electrolysis in a smelter using the energy-intensive Hall-Heroult process Bauxite formation Bauxite ,
Primary aluminum production begins with the mining of bauxite ore, a hydrated oxide of aluminum consisting of 30 to 56 percent alumina (A l2O3) and lesser amounts of iron, silicon, and titanium The ore is refined into alumina by the Bayer process The alumina is then shipped to a primary aluminum plant for electrolytic reduction to aluminum The ,

The production of aluminum from bauxite is a two-step process: refining bauxite to obtain alumina and smelting alumina to produce aluminum Bauxite contains a number of impurities, including iron oxide, silica, and titania If these impurities are not removed during refining, they will alloy with and contaminate the metal during the smelting process,
The common raw material for aluminium production, bauxite is composed primarily of one or more aluminium hydroxide compounds, plus silica, iron and titanium oxides as the main impuriti It is used to produce aluminium oxide through the Bayer chemical process and subsequently aluminium through the Hall-Heroult electrolytic Process On a world-wide average 4 to 5 tonnes of bauxite ,
