Aluminum is an abundant (2) metal (1) that has many uses (3). It comes from bauxite (4) which is an ore (5). Bauxite looks like clay (6) and contains aluminum (7) and several (8) other substances (9). Workers extract the other substances from the bauxite (10) and (1) then grind (11) it. It is then put (12) in pressurized (13) tanks. The other substances form a mass (14) which is removed (15) by filters (16). A liquid remains (17) which is put through several other processes (18) which yields a chemical (19). The chemical is a white (21) powder (20) which is alumina (22). It is a mixture (23) that contains aluminum (24) and oxygen (25). They seperate the aluminum from the oxygen (26) with electricity (27). It finally produces a metal (28). The metal is light (29) has a luster (30) and comes in many forms (33).
