Aluminum Smelting Furnaces and Processing of Bauxite Ore
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

Bauxite Mining Encyclopedia of Arkansas
Bauxite is the principal ore of aluminum and is a mixture of aluminum oxides and hydroxides that formed from intense chemical weathering of a soil in tropical environments. Soils formed under these conditions are termed laterites. In Arkansas, the aluminumenriched soils are the result of the decomposition and lateritic weathering of nepheline syenite, an intrusive igneous rock. During the
