aluminium (US: aluminum)
The usual aluminium ore is bauxite. Bauxite is essentially an impure aluminium oxide. The major impurities include iron oxides, silicon dioxide and titanium dioxide. These range from NaAlO 2 (which is a dehydrated form of the one in the equation) to Na 3 Al(OH) 6 (which is a different product altogether).
