Bauxite ore is the world’s main source of aluminum. Bauxite is a rock formed from a reddish clay material called laterite soil and is most commonly found in tropical or subtropical regions. Bauxite is primarily comprised of aluminum oxide compounds (alumina), silica, iron oxides and titanium dioxide. Approximately 70 percent of the world’sPrimary 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 12.1 Primary Aluminum Production U.S. Environmental

Mining has advanced primarily through the use of two strategies: pyrometallurgy and hydrometallurgy. Both have been used successfully to extract valuable metals from ore deposits. These strategies, without a doubt, harm the environment. Furthermore, due to decades of excessive mining, there has been a global decline in Aluminium Ore. Bauxite is the principal ore of Aluminium. From bauxite, alumina is extracted and from alumina, aluminium is extracted. Aluminum is a good conductor of electricity. It is highly malleable. Bauxite (raw material) is bulky, and it is preferable to remove moisture and impurities before transporting its ore over long Aluminium Ore, Bauxite, Uses, Properties, Distribution Map
