Bauxite Mineral

Bauxite mineral is the primary ore of aluminium.

It is actually a mixture of a few different minerals, but it is not a rock (rocks normally consist of different minerals).

It is a kind of laterite - a loose weathered material that consists of a few different minerals, including aluminium and iron oxides and hydroxides (including gibbsite, diaspore and boehmite).

Other minerals that may be present include quartz, siderite, goethite, magnetite, hematite, and clay minerals.


It is most often reddish brown in colour, but can also be yellowish, whiteish, pinkish or grey. It is most often massive in habit, and it can be quite soft or quite hard to crush.

  bauxite mineral

It forms from many different rocks that are rich in aluminium silicates in warm and humid climate typical for tropical rainforests.

  bauxite deposit 

In that kind of warm and wet climate, other minerals are washed away by chemical weathering, while
aluminium and iron oxides and hydroxides are left behind.

  bauxite residue

This makes bauxite an excellent Aluminium ore - 99% of the aluminium in the world is produced from bauxite.

  bauxite ore 

It was first discovered in southern France, where it was named after the town of Les Baux de Provence.

  bauxite to aluminium 

Today, about 40% of all world's bauxite comes from Australia, and mainly from the world's largest bauxite mine in Weipa on Cape York peninsula.

Other places in Australia include Darling Range in Western Australia and Gove in Northern Territory.

 bauxite mines

Some other tropical countries such as India, Jamaica, Brazil and New Guinea also have some bauxite.

Some bauxite is also found in the US, China, Ghana, Greece, Italy and France.
