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.

Bauxite ore is soft and red clay, rich in alumina, and its name originates from Les Baux de Provence, It was a French geologist Pierre Berthier who first discovered bauxite near a village southern France in 1821. Later, a French chemist named Henri Sainte-Claire Deville officially termed the substance as "bauxite" in 1861.

In the bauxite refining process, the aluminum-bearing minerals in bauxite are converted in a multiple-step process to alumina (Al2O3). Alumina can be smelted to form metallic aluminum or it can be used as the source of many other products, including refractory materials used to line high-temperature rotary kilns and metallurgical furnaces.
