Aluminum is a metal (1) that is very common (2) and has many uses (3). Aluminum comes from Bauxite (4) which is an ore (5). Bauxite looks like clay (6) and contains aluminum (7) and several (8) other substances (9). Workmen extract these other substances from Bauxite (10). The Workmen then (1) grind (11) the bauxite and the place (12) it in pressurized (13) tanks. The other substances leaves a mass (14) which is removed (15) through filters (16) leaving it in a liquid (17) state. They then put it through several other processes (18) which finally yields (19) a chemical. Alumina (22), a powdery (20) white (21) chemical is produced. Alumina is a mixture (23) that contains aluminum (24) and oxygen (25). Workmen seperate the Aluminuim from the oxygen (26) with electricity (27). They finally produce a light (29) metal (28) that has a bright (31), silvery (32) luster (30). This type of metal comes in several different varities (33).
