Aluminum is an abundant (2) and versitile (3) metal (1) that comes from bauxite (4). Bauxite is an ore (5) that resembles clay (6) and contains aluminum (7) and several (8) other substances (9). Workmen extract these other substances (10) and (1) grind (11) the bauxite before putting (12) them into pressure (13) tanks. The leftover substances form a mass (14) that gets removed (15) through filters (16) until a liquid remains (17). After several other processes (18) a powdery (20), white (21) chemical is left (19). This chemical is known as alumina (22), this is a mix (23) of aluminum (24) and oxygen (25). By using electricity (27), workmen seperate the aluminum from the oxygen (26). Finally, a light (29) metal is yielded (28) that has a silvery (32) luster (30). This metal comes in many forms (33).
