Aluminum is an abundant (2) metal (1) with many uses (3). It comes from (4) an ore (5) called bauxite which looks like clay (6) and is made up of many (8) different substances (9). Workmen extract the other substances (10) by grinding (11) the ore and placing (12) it into pressurized (13) tanks. This causes (1) the unwanted material to form a mass (14) which can be removed (15) using filters (16) leaving a liquid (17). Through several other process (18) they are able to yield (19) a powdery (20) chemical called alumina (22) containing aluminum (24) and oxygen (25). It is then seperated from the oxygen (26) using electricity (27) creating (28) a light (29), bright (31) metal with a silvery (32) luster (30).
