What the source says
Primary aluminum reduction plants electrolytically reduce refined bauxite to form aluminum. Once formed, the aluminum may be processed via casting (pouring molten aluminum into a mold), rolling, extrusion, etc. to meet the shape, strength and durability requirements of its final use. Aluminum is used extensively in consumer packaging (e.g., cans and foil), transportation applications (e.g., cars, planes and trains) and in the building industry.
