Aluminum is an abundant (2) metal (1) that comes from (4) bauxite. which is an ore (5) that looks like clay (6) and also contains aluminum (7). Bauxite also contains many (8) other substances (9). Workmen extract these substance (10) when they grind (11) the Bauxite. They put it in tanks (12), then add pressure (13), and the substances form a mass (14). The mass is then removed (15) with filters (16) and the liquid remains (17). After that it goes through many other processes (18) until it finally yields a chemical (19). The chemical is powdery (20) and white (21). The chemical is alumina (22) and is a mixture (23) of aluminum (24) and oxygen (25). Workmen then separate them (26) and use them for (1) electricity (27). After this it becomes a metal (28). The metal is a silvery (32) bright (31) luster (30) and comes in many forms (33).
