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. The aluminum minerals in bauxite can include: gibbsite Al(OH)3, boehmite … See more
What is Bauxite? Bauxite is primarily a metallic mineral though it is also used as an industrial mineral. It is the only ore used for large-scale aluminium production. Although aluminium is the most abundant metallic element in the earth's crust constituting about 8%, it usually occurs in clays, soil and rocks that cannot be utilised for its extraction.

Bauxite is a mineral that is abundant in the world. It is found mostly in Africa, South America, and Australia. Bauxite mining uses water to clean and separate the ore from other rocks, which makes it an environmentally-friendly process. Additionally, bauxite has been mined for over 3,000 years, making its history long.
The principal minerals in bauxite are gibbsite (Al 2 O 3.3H 2 O), boehmite (Al 2 O 3.H 2 O) and diaspore, which has the same composition as boehmite but is denser and harder. Bauxite is usually classified according to its intended commercial application, e.g., metallurgical, cement, fertiliser, abrasive, chemical or refractory.

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.
