Bauxite mining Aluminium metal and aluminium products

Bauxite mining. Aluminium production starts with the raw material bauxite. Bauxite is a mineral found mostly in a belt around the equator. Bauxite, containing 1525 percent aluminium, is the only ore that is used for commercial extraction of aluminium today.

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 stripmining operations.

How Aluminum Works. Molten aluminum metal sinks to the bottom of the vat and is drained periodically through a plug. The alumin173;um smelting process developed by Hall resulted in large amounts of pure aluminum. Suddenly, the metal was no longer rare. The idea of producing aluminum via electrolytic reduction in cryolite wasn't rare, either.

How Aluminum Works. The first step in the commercial production of aluminum is the separation of aluminum oxide from the iron oxide in bauxite. This is accomplished using a technique developed by Karl Joseph Bayer, an Austrian chemist, in 1888. In the Bayer process, bauxite is mixed with caustic soda, or sodium hydroxide, and heated under pressure.
