Aluminum is an abundant (2) metal (1) that has many uses (3). Aluminum comes from bauxite (4), an ore (5) that has some clay-like (6) features. Workmen grind (11) the bauxite then place (12) it into pressurized (13) tanks. They then use filters (16) to seperate (15) the two substances which remain. They take the liquid that remains (17) and put it through several other processes (18) which finally yields (19) a white (21) powdery (20) chemical. The chemical that forms, alumina (22), is a mixture (23) of aluminum (24) and oxygen (25). Workmen use electricity (27) to seperate the aluminum from the oxygen (26). The product that forms is a light-weight (29), shiney (31), silver-colored (32) metal (28) which is called aluminum (1).
