Aluminum is a metal (1) that is abundant (2), has many uses (3), and it comes from (4) bauxite. Bauxite is an ore (5) that looks like clay (6) and contains aluminum (7) as well as several (8) other substances (9) from bauxite (1). They grind (11) the bauxite and put it into tanks (12), which are pressurized (13). The substances in the tank form a mass (14), and after the mass forms (1) they use filters (16) to empty the tank (2). A liquid remains (17) now, and after several other processes (18) it finally yields a chemical (19). The chemical is a white (21) powder (20) that is a mixture (23) of (3) alumina (22) containing aluminum (24) and oxygen (25). Workmen seperate the aluminum from the oxygen (26), and after (4) using electricity (27) they produce the metal (28). The aluminum is light (29) with a luster (30) that is bright (31) and silvery (32). Now the metal can be made into many forms (33).
