     Aluminum is an abundant (2) metal (1) that has many uses (3). Aluminum is derived from Bauxite (4), which is an ore (5) that looks like clay (6); contains many (8) subtances (9). Workers grind (11) the bauxite and put (12) it in pressurized (13) tanks. The workers remove (15) the mass using filters (16), which cause the substances to produce a liquid (17). The substances are then put into several other processes (18) until it produces a chemical (19), which is a white (21) powder (20).
