Bauxite occurs mainly in the tropics and in some Mediterranean countries. Today, the main mining locations are in Latin America, Australia, India, and Africa. Bauxite is a weathered rock containing two forms of hydrated aluminum oxide, either mostly a monohydrate AlO(OH) in caustic bauxite, or mostly a trihydrate Al(OH) 3 in lateric bauxite.
Before the digestion, addition of 2.11% lime to the bauxite samples decreases the alumina recovery and increases the Na 2 O/SiO 2 ratio of red mud with increase in temperature. The highest alumina recovery and the lowest Na 2 O/SiO 2 ratio were achieved at 240 °C. It can be explained that lime partly reacts with silica in the bauxite and prevents sodium silicate …

Primary aluminum production begins with the mining of bauxite ore, a hydrated oxide of aluminum consisting of 30 to 56 percent alumina (A l2O3) and lesser amounts of iron, silicon, and titanium. The ore is refined into alumina by the Bayer process. The alumina is then shipped to a primary aluminum plant for electrolytic reduction to aluminum.
