Aluminum is an abundant (2) metal (1) which has many uses (3). Aluminum comes from bauxite (4), which is an ore (5). Bauxite contains several (8) other substances (9) , as well as aluminum (7). Workmen extract these substances from the bauxite (10) by grinding (11) it. Then, the workmen put (12) the bauxite in a pressure (13) tank. The other substances found in the bauxite (1) form a mass (14), which is removed (15) through filters (16). Now there is only a liquid that remains (17). The workmen put this liquid through other processes (18), until it yields (19) a powdery (20), white (21), chemical. This chemical is called alumina (22). Alumina is a mixture (23) that contains aluminum (24) and oxygen (25), and the workmen seperate them. (26) using electricity (27).
