Aluminum is an abundant (2) metal (1) with many uses (3). It is contained (4) in an ore (5) called bauxite, which looks like clay (6). Bauxite also contain several (8) other substances (9) which are extracted by workmen (10). The workmen grind (11) the bauxite and place it (12) into pressured (13) tanks. The other substances form a mass (14), which is removed (15) through filters (16). A liquid remains (17) and is put through several other processes (18). Finally it yields (19) a white (21), powdery (20) chemical called alumina (22). This is a mixture (23) that contains aluminum (24) and oxygen (25). The two are separated (26) using electricity (27) to produce a metal (28). The metal is light (29), with a bright (31), silvery (32) luster (30), and comes in many forms (33).
