Aluminum is a abundant (2) metal (1) that comes from bauxite (4). Bauxite is a ore (5) that looks like clay (6) and contains aluminum (7) along with many (8) other substances (9). Workmen extract these other substances (10) by grinding (11) the bauxite and putting (12) it in pressurized (13) tanks. The workers remove (15) the unwanted materials with filters (16) as a result (1) a liquid remains (17). They put the liquid through more processes (18) which yeilds (19) a powdery (20) white (21) chemical. The chemical is alumina (22) which is a mixture (23) of aluminum (24) and oxygen (25). Workmen use electricity (27) to separate the aluminum from the oxygen (26). They finally produce a light (29), bright (31), silvery (32) metal (28) that comes in many forms (33).
