Named after a region of Greece, magnesium is a silverywhite, shiny metal. It is ductile and fairly soft, although nowhere near as soft as sodium or lithiu
Two to three tonnes of bauxite are required to produce one tonne of alumina. 90% of the global alumina supply of around 90 million tonnes is used in aluminium production. Alumina refineries tend to be located close to bauxite mines and/or ports for efficient transport of raw materials and of the final product.

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.
Bauxite ore is the world''s primary source of aluminum. 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.
Aluminum ore, commonly called bauxite, is mined in Australia (the top producer) China, Brazil, Guinea, and India.
