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. PropertiesMar 11, 2019 Bauxite ore contains 30-60% aluminum oxide (Al 2 O 3). In the Bayer process (Figure 2), the bauxite is digested in a pressure vessel along with a sodium hydroxide solution (caustic soda) at an elevated temperature, which dissolves the aluminum oxide converting it into sodium aluminate, leaving insoluble red mud solids as a by-product.

Bauxite: The principal ore of aluminum.

Bauxite: The principal ore of aluminum.

Aluminum. Aluminum is the most abundant metal element in the Earth’s crust. 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.The World's Leading Bauxite Producing Countries. Australia is the world's leading producer of bauxite, an aluminium ore that is used as the primary source of the metal. A Bauxite mining facility in Queensland, Australia. Note the color of the soil, reflecting the presence of the reddish brown Bauxite in high concentrations here.
