Aluminium Mining Techniques Mines Occurence Processing

Aluminium is the most profuse metallic part in the earths crust It is mined from bauxite contained mining areas since the production of aluminium is entirely reliable on extraction from bauxite It is not found in free form and is the most abundant metallic element in the Earth s crust Alumininum is basically obtained by using a technique called the Bayer s process developed by Karl Joseph

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
