Bauxite was first discovered in 1821 near the village of Les Baux in southern France, from which it derives its name.
It is a mixture of aluminum oxide and hydroxides with a hardness of 1 to 3 and a density of 2.5 to 3.5 g/cm³.Its chemical formula is usually 'Al2O3NH2O'. However, the formula can change since the minerals inside differ.It is usually found as and in the form of oolitic, massive, soil and clay.Depending on the amount of iron it contains, its color can be white, yellow, green, gray, red or brown.
99% of the aluminum production in the world is obtained from this ore and bauxite production is increasing in parallel with the aluminum demand. In addition, bauxite is frequently used in the cement, iron and steel, refractory and abrasive industries. In this respect, bauxite ore has an important place in world trade.
