Processing Of Bauxite Ore

Processing of Bauxite Ores To Obtain Aluminum Bauxite, the primary aluminum ore, uses the Bayer Process to extract alumina from the ore. The processing begins with crushing to 1-2 inch particles and wet screening, to remove some silica fines, which are generally present with bauxite

    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
