The electrolytic extraction of aluminium from bauxite and alumina is an industrial process that produces and refines aluminium into its pure form as a metal
Bauxite Used for Aluminum Production. 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…
Alumina is properly called aluminum oxide, which is a chemical compound comprised of aluminum and oxygen molecules (Al 2 O 3). When refined from bauxite, alumina generally looks like a white powder similar to table salt or granular sugar. Aluminum oxide is typically referred to as alumina, but may also be called aloxide, aloxite or alundum, depending on the industry and the metal's use.

Bauxite(above) is an aluminium ore and is the main source of aluminium.This form of rock consists mostly of the minerals gibbsite (aluminium hydroxide), 2 aluminium oxide hydroxides (boehmite and diaspore) in a mixture with the two iron oxides (goethite and hematite), the clay mineral kaolinite, and small amounts of anatase(one of the mineral forms of titanium dioxide). Extraction process ...
Primary Production The Aluminum Association. Quick Read. Primary production is the process by which alumina is smelted to pure aluminum metal. The HallHéroult process, simultaneously discovered in 1886 by American Charles Martin Hall and Frenchman Paul Héroult, continues as the main industrial process by which primary aluminum is made.
