BAUXITE ORE
Bauxite, an aluminum ore, is the worlds main source of aluminum. It consists mostly of the minerals gibbsite Al (OH)3, boehmite γ-AlO (OH) and diaspora α-AlO (OH), mixed with the two iron oxides goethite and haematite, the clay mineral kaolinite and small amounts of anatase TiO2, Ilmenite, FeTiO3, and FeO TiO2.

Bauxite does not have a specific composition. It is a mixture of hydrous aluminum oxides, aluminum hydroxides, clay minerals, and insoluble materials such as quartz, hematite, magnetite, siderite, and goethite. Bauxite is the principal ore of aluminum. The first step in producing aluminum is to crush the bauxite and purify it using the Bayer Process. In the Bayer Process, the bauxite is washed in a hot …
Bauxite - an overview | ScienceDirect Topics
The bauxite is friable and reddish-brown, contains boulders of all sizes up to 12 m diameter of gabbro, which would hinder mining. The core of the boulders is fresh, with a thin skin of bauxite. The bauxite ranged from 45–53% A1 2 O 3 and contains 64–78 % gibbsite. A thick bed of kaolinite, goethite and some gibbsite underlies the bauxite.
