The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide). Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide, (alumina), Al 2 O 3, the rest being a mixture of silica, various iron oxides, and titanium dioxide.

Bauxite is the primary source of aluminium metal, and about 85% of bauxite mined is processed via the Bayer Process to make alumina trihydrate (ATH), then smelter grade alumina (SGA) from which aluminium metal is derived.

Bayer Today the Bayer process dominates the production of alumina as it is the lowest cost production route. The process uses a recirculating volume of concentrated caustic solution to dissolve the alumina minerals, separate them from still solid impurities, and then re-precipitate alumina tri-hydrate.

Bauxite is a naturally occurring, heterogeneous material composed primarily of one or more aluminum hydroxide minerals, plus various mixtures of silica, iron oxide, titania, …

Bauxite is the primary mineral for alumina and thus ultimately aluminium production. It is named after the town of Les Beaux in southern France, where the chemist Berthier first recognised it in 1821.

There have been a number of attempts to combine Bayer and Sinter technologies in an effort to find an economic means of processing low grade bauxite. To date none of these has really proved that successful and all bar some …

In 2011 nearly 260 million tonnes of bauxite was produced world wide. The majority of this material was consumed in-country for the production of smelter grade alumna. The one outlier in this respect is Indonesia which, with no …
