Aluminum is an abundant (2) metal (1) which has many uses (3). It comes from (4) an ore (5) called bauxite. Bauxite is a clay like (6) substance which contains aluminum (7) and other substances (9). Scientists (1) extract these other substances from the bauxite (10). They then (1) grind (11) the bauxite and put (12) it in pressurized (13) tanks. They then use filters (16) to remove (15) the mass of the other substances. The scientists proceed to put the remaining liquid (17) through several other processes (18), and finally a chemical is yielded (19). The chemical that is produced (2) is a powdery (20), white (21) mixture (23) called alumina (22). Alumina contains aluminum (24) and oxygen (25) which scientists seperate (26) using electricity (27). They finally produce (28) a light (29) metal with a bright (31), silvery (32) luster (30). Aluminum can then be used in many forms (33).
