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.
When our bauxite mine in the Republic of Guinea starts commercial production, we will become a global supplier of bauxite. Our concession in Guinea contains some 1.4 billion tonnes of high-quality bauxite resources.
Our bauxite is relatively high in Gibbsite and low in Bohemite, reactive silica and organic impurities. Along with the fact that we will produce both low temperature and high temperature bauxite, this means it will be able to be processed by a wide variety of alumina refineries.
