Bayer Process: Manufacturing Of Alumina - Making of AluminaAluminum Smelting Furnaces and Processing of Bauxite Ore

The Bayer Process: Alumina is the main components of bauxite, so bauxite is refined in order to produce Alumina The Bayer process is the principal way for producing alumina by refining Bauxite Bauxite other than with 30-60percentage of aluminium oxide contains mixture of ,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.
