Aluminum is an abundant (2) metal (1) with many uses (3). Aluminum comes from (4) an ore (5) called Bauxite. Bauxite looks like clay (6) and contains aluminum (7) and several (8) other substances (9). workmen extract these other substances (10) then (1)grind (11) the Bauxite. They then put (12) the Bauxite in pressurized (13) tanks. In the tanks the other substances form a mass (14), this mass is then removed (15) by use of filters (16). All that is left is a liquid (17) that they process several times (18) to create (19) a powdery (20) white (21) chemical, this is alumina (22). Alumina is a mixture (23) of aluminum (24) and oxygen (25) that is seperated (26) using electricity (27). The final product is a shinny (31) and light (29) metal (28) that is silvery (32).
