Aluminum is an abundant (2) metal (1) with many uses (3). It comes from (4) the ore (5) Bauxite which looks like clay (6). Bauxite contains aluminum (7) along with several (8) other substances (9). Workmen, extract these other substances from the bauxite (10), grind (11) it, and (1) put (12) it into pressurized (13) tanks. The other substances, form a mass (14) which is then removed (15) by use of filters (16), leaving only a liquid (17). It is then put through several other processes (18) finally yielding (19) a white (21), powdery (20) chemical called alumina (22). It is a mixture (23) containing aluminum (24) and oxygen (25). Workmen separate the aluminum from the oxygen (26) by using electricity (27). This produces a light (29) metal (28) with of (2) bright (31) silvery (32) luster (30). This metal comes in many forms (33).
