Bauxite ore is the most common raw material used for producing alumina, which is the feedstock for aluminium smelting. Bauxite is a group of aluminium oxides.
Bauxite is named after the town of Les Baux-en-Provence in France, which is where the geologist Pierre Berthier first identified the mineral in 1821.
Aluminium is the third most abundant metal found in the Earth’s crust but it is never found free in nature. It has always reacted with other elements to form compounds such as aluminium oxides.
Deposits of bauxite tend to be found in tropical areas where it is formed through the weathering of aluminium-rich rocks over millions of years. The largest concentration of high quality bauxite is found in the north-west of the Republic of Guinea.
Emirates Global Aluminium’s Guinea Alumina Corporation bauxite mine in the Republic of Guinea is a global supplier of bauxite.
Our bauxite is relatively high in Gibbsite and low in Bohemite, reactive silica and organic impurities. We produce both low temperature and high temperature bauxite, meaning our bauxite is able to be processed by a wide variety of alumina refineries.
