Bauxite Ore Mining Extraction Process

Aluminum Smelting Furnaces and Processing of Bauxite Ore

Apr 06 2010 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
