how is aluminium made from its ore

  • What Aluminum Extraction Really Does to the Environment

    Nov 09, 2010Of all the earth's natural elements, aluminum happens to be the third most abundant resource on our planet in its raw form. With rather humble origins as a soft, red, mineral-laden rock called bauxite, highly valuable aluminum ore contains boehmite, diaspore and gibbsite as well as clay, iron hydroxides and free silica.

  • How is aluminium extracted from its ore using electrolysis

    Nov 05, 2008My understanding is that it is a basic reduction process. Aluminum exists as a cation in the ore, obtaining its needed electrons from its associated anions (typically oxygen or hydroxide). During extraction, electrons are provided to the ore that convert the Al from the Al+3 cation to native Al.

  • How aluminium is produced

    Aluminium alloys are made by mixing aluminium with various other metals (the so-called alloying elements). Some increase the strength of aluminium, others make it denser, still others change its heat transmission properties, etc. Common alloying elements include boron, iron, silicon, magnesium, manganese, copper, nickel, lead, titanium, chromium, zinc, zirconium, lithium, scandium, silver and

  • Mining and Refining Aluminum

    The primary source of aluminum is an ore known as bauxite. An ore is any naturally occurring solid material from which a metal or valuable mineral can be obtained. In this case, the solid material is a mixture of hydrated aluminum oxide and hydrated iron oxide. Hydrated refers to water molecules that are chemically bound to the two compounds.

    Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as "beneficiation", which include washing, wet screening and mechanical or manual sorting.

  • Bauxite: The principal ore of aluminum.

    Bauxite is the principal ore of aluminum. The first step in producing aluminum is to crush the bauxite and purify it using the Bayer Process. In the Bayer Process, the bauxite is washed in a hot solution of sodium hydroxide, which leaches aluminum from the bauxite. The aluminum is precipitated out of solution in the form of aluminum hydroxide, Al(OH) 3.
