Aluminum is an abundant (2) metal (1) with many uses (3). Aluminum comes from (4) a clay like (6) ore (5) known as Bauxite. Bauxite also contains several (8) other substances (9), not only aluminum (7). Workmen extract the other substances from the bauxite (10), then (1) grind (11) the bauxite. They put (12) the bauxite in pressurized (13) tanks to form a mass (14). They remove (15) the mass and (2) the liquid is filtered (16), and sent through several other processes (18). This yields (19) a white (21), powdery (20), chemical, which is known as alumina (22). Alumina is a mixture (23) containing aluminum (24) and oxygen (25). Workers use electricity (27) to seperate (26) the aluminum from the oxygen to produce aluminum (28). The finished aluminum has a bright (31), silvery (32), luster (30), and is light (29) in weight (1). The aluminum comes in many different forms (33) which can be used just about anywhere (2).
