Aluminium life cycle. The main raw material for aluminium production is bauxite. Aluminium oxide is extracted from the bauxite, and is used in an electrolytic reduction process to produce primary aluminium. It takes roughly 47 metric tons of bauxite to produce 2 metric tons of alumina, which then yields 1 metric ton of aluminium.
