The process of making aluminium starts with the mining of bauxite. Bauxite is the mineral form of aluminium and is made up of approximately 50 per cent alumina. Bauxite deposits are generally found about one metre underground and are around three to four metres deep. Bauxite is mined as small red pebbles called pisolites.
