Bauxite The principal ore of aluminumHow aluminium is produced

Other materials could be used instead of bauxite for alumina production Clay minerals alunite anorthosite power plant ash and oil shale could be used to produce alumina but at higher costs using different process Silicon carbide and synthetic corundum are sometimes used in place of bauxite based abrasivThe next stage in the production chain is the processing of bauxite into alumina or aluminium oxide Al 2 O 3 a white powderThe most common process for making alumina from bauxite is the Bayer process which was first discovered over 100 years ago but is still in wide use today
