Aluminum facts - NRCan

2021-11-29  Production. Aluminum does not exist in a pure state in nature. The production of primary aluminum metal begins with bauxite ore, which is composed of hydrated aluminum oxide (40% to 60%) mixed with silica and iron oxide. It takes approximately 4 to 5 tonnes of bauxite ore to produce 2 tonnes of alumina.
