Bauxite is an important ore of aluminum, composed mainly of aluminum oxide and hydroxide minerals. It was named after the village Les Baux-de-Provence in southern France, where it was first discovered in 1821 by geologist Henri Rouvère. Bauxites have a range of commercial applications, such as for the production of aluminum metal and …
Bauxite is an aluminium-rich ore used for the manufacture of aluminium (metallurgical bauxite) and refractory products, chemicals or cements. Bauxite is a prime important raw material for the primary aluminium industry. It is also used in a number of non-metallurgical sectors, like refractory, abrasive, cement, steel making and chemicals.
The gibbsite content of Jamaican bauxite ranges from 34-46%, whereas boehmite can range from 1-12%. For this reason, Jamaican bauxite may be classified as `mixed' trihydrate/monohydrate or gibbsite/boehmite bauxite. Some amount of blending can be tolerated in the processing, and this is encouraged in order to maximize use of the …

Bauxite (Fig. 1.33) is formed by surface weathering of clay rocks around the tropical region and composer of aluminum oxide (Al (OH) 3 ). It contains 15%–25% aluminum and only ore used for commercial extraction for aluminum. The bauxite occurs as near-surface layers and usually mixed with clay minerals, iron oxide, and titanium dioxide.
