Aluminum is an abundant (2) metal (1) which has many uses (3). It comes from (4) an ore called Bauxite (5). This ore looks like clay (6) and contains several other (8) substances (9). Workers extract other substances (10) by grinding (11) it and putting (12) it into pressurized (13) tanks. From the pressure in the tanks (1) a mass is formed (14). This mass is then removed (15) with a filter (16) which leaves only water (1) remaining (17). After going through several other processes (18) it yields a white (21), powdery (20) chemical (19). The chemical formed, alumina (22), is a mixture (23) of aluminum (24) and oxygen (25). This is then seperated (26) by electricity (27) and produces a metal (28). This metal is light (29), luster (2), and comes in many forms (33). The luster (30) of this metal is both bright (31) and silvery (32).
