    Bauxite The Aluminum Association

    ResourcesEnvironmentFutureDiscoveryBauxite ore is the worlds primary source of aluminum. The ore must first be chemically processed to produce alumina (aluminum oxide). Alumina is then smelted using an electrolysis process to produce pure aluminum metal. Bauxite is typically found in topsoil located in various tropical and subtropical regions. The ore is acquired through environmentally responsible strip-mining operations. Bauxite reserves are most plentiful in Africa, Oceania and South America. Reserves are projected to last for ce

    Mining and Refining Process - World Aluminium

    The bauxite residue sinks to the bottom of the settling tanks, then is transferred to the washing tanks, where it undergoes a series of washing stages to recover the caustic soda (which is reused in the digestion process). Further separation of the pregnant liquor from the bauxite residue is performed utilising a series of security filters.

    Mining and Refining Aluminum HowStuffWorks

    CompositionGeologyProductionUsesAluminum isn't found in nature as a pure element. It exhibits relatively high chemical reactivity, which means it tends to bond with other elements to form compounds. More than 270 minerals in Earth's rocks and soils contain aluminum compounds. This makes aluminum the most abundant metal and the third most abundant element in Earth's crust. Only silicon and oxygen are more common than aluminum.

    Jan 07, 2018  Bauxite is the primary feedstock for an alumina refinery to extract aluminium oxide using the Bayer process. Generally, around 2 to 3 tonnes of bauxite is required to produce one tonne of alumina. Aluminium metal is subsequently extracted from alumina in a smelter via electrolysis through the Hall-Heroult method.
