2.2.1. Mining process. Aluminium is rarely found in its elemental form and so requires extraction in order to produce the quantity in demand. The principal ore used for aluminium extraction is bauxite, accountable for more than 99% of primary aluminium production [12].Bauxite ore is mined predominantly from open cast mines on the earth's surface [18, 20].
