Aluminum is a metal (1) that is abundant (2) which has many uses (3). It comes from (4) a ore (5) called Bauxite which looks like clay (6). Bauxite not only contains aluminum (7), but many (8) other substances (9). Workmen try to get rid of the other substances (10?) by grinding (11) it, and then putting (12) the Bauxite into pressure (13) tanks which makes a mass (14) which is removed (15). Then they use filters (16) till a liquid remains (17). Next they put it through several more processes (18). Finally a white (21) powdery (20) chemical appears (19) that is alumina (22). The mixture (23) contains aluminum (24) and oxygen (25) that needs to be separated (26). The workmen use electricity (27) to produce a metal (28) that is light (29), bright (31), silvery (32) and (1) luster (30). Aluminum comes in many forms (33).
