  • 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.

    Aluminum, or aluminium (Al), is a silvery white metal with a melting point of 660 °C (1,220 °F) and a density of 2.7 grams per cubic cm. The most abundant metallic element, it constitutes 8.1 percent of Earth’s crust. In nature it occurs chemically combined with oxygen and other elements. In the pure state it is soft and ductile, but it can be alloyed with many other elements to increase ...

Bauxite ore is the main source of aluminum and contains the aluminum minerals gibbsite, boehmite, and diaspore. Aluminum is used in the United States in packaging, transportation, and building. Because it is a mixture of minerals, bauxite itself is a rock, not a mineral. Bauxite is reddish-brown, white, tan, and tan-yellow.

    Aluminium is the most profuse metallic part in the earths crust. It is mined from bauxite-contained mining areas since the production of aluminium is entirely reliable on extraction from bauxite. It is not found in free form and is the most abundant metallic element in the Earth's crust. Alumininum is basically obtained by using a technique called the Bayer's process developed by Karl Joseph ...

  • Aluminum industry in the United States - Wikipedia

    The principal raw materials for aluminum production are bauxite (for primary production) and scrap (for secondary production). Primary aluminum production consumes a great deal of electricity, which makes up about a third of the cost. Making a ton of primary aluminum consumes at least 12,500 kW-hr, and most plants consume 14,500 to 15,000 kW-hr ...

    Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH)3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe2O3), the aluminium clay mineral kaolinite (Al2Si2O5(OH)) and small amounts of anatase (TiO2) and ilmenite (FeTiO3 or FeO.TiO2).

    Electrical current is passed through the molten material. At the cathode, electrolysis reduces aluminum ions to aluminum metal. At the anode, carbon is oxidized to form carbon dioxide gas. The overall reaction is: 2Al 2 ­O 3 + 3C -> 4Al + 3CO 2 ­ Molten aluminum metal sinks to the bottom of the vat and is drained periodically through a plug.

    Aluminium can be extracted (uneconomically) from some clays but the most common aluminium ore is a material called bauxite. First the aluminium ore needs to be mined, then the bauxite is refined into alumina (aluminium oxide). Large amounts of electricity are used to smelt the alumina into aluminium metal. Properties
