Aluminum is an abundant (2) metal (1) that has many uses (3). This metal comes from bauxite (4) which is ore (5) that looks like clay (6). Bauxite contains aluminum (7) along with several (8) other substances (9). Workmen extract these substances (10) by first grinding (11) them and then putting (12) them in a pressurized (13) tank. The substances remaining form a mas (14) which is then filtered (16) and a liquid remains (17). After several other processes (18) it yields (19) a white (21), powdery (20) chemical. The chemical remaining is alumina (22) that contains aluminum (24) and oxygen (25). The oxygen is seperate (26) by electricity (27). Finally, a metal (28) with (1) light (29) and luster (30) that is bright (31) and silvery (32) is formed
