Aluminum is an abundent (2) metal (1) that comes in many forms (33) and has many uses (3). It comes from (4) a claylike (6) ore (5) called bauxite. Bauxite contains several (8) other substances (9). To remove these substances (10) workers grind (11) up the bauxite and place (12) it in presurized (13) tanks. The other substances form a mass (14) and are removed (15) with filters (16). After that, only a liquid remains (17). After putting the liquid through several other processes (18), it finally yields (19) a white (21), powdery (20) chemical. Workers then separate the aluminum from the oxygen (26) using electricity (27). They finally produce a light (29) metal (28) with a bright (31) silvery (32) luster (30).
