In nature, aluminum does not exist in a pure state. The production of primary aluminum metal begins with bauxite ore, which is composed of hydrated aluminum oxide (40% to 60%) mixed with silica and iron oxide. It takes about 4 to 5 tonnes of bauxite ore to produce approximately 2 tonnes of alumina.
The smelting of aluminum begins with the extraction of bauxite ore by a form of open cast mining. The bauxite is washed and screened before being converted to alumina, a white powdery element from which the aluminum is produced. Aluminum smelting is carried out in a Hall Heroult reduction cell, which is lined with carbon. A mix of alumina and cryolite is fed into the cell and carbon blocks ...
