Aluminum facts | Natural Resources Canada

In nature, aluminum does not exist in a pure state. 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 about 4 to 5 tonnes of bauxite ore to produce approximately 2 tonnes of alumina.
