  • Aluminium Bauxite Ore Fields

aluminium (US aluminum)

The ore is first converted into pure aluminium oxide by the Bayer Process and this is then electrolysed in solution in molten cryolite - another aluminium compound The aluminium oxide has too high a melting point to electrolyse on its own Aluminium ore The usual aluminium ore is bauxite Bauxite is essentially an impure aluminium oxide

Why aren't bauxite or aluminum magnetic?

Aluminum is magnetic It is what we call a paramagnet This is because its atoms have an unpaired electron giving them a magnetic field In the presence of a strong external magnetic field those atoms will align and aluminum will have an overall magnetic field and be attracted to a magnet
