     Aluminum is a unique (1) metal (1). It is abundant (2) with it's many uses (3). It comes from (4) the ore (5) bauxite. Bauxite is a container for many (8) other substances (9) inside it. The aluminum is grinded (11) from the bauxite so it is able to be used as a product (2). The bauxite has to be inside (12) pressure (13) tanks in order to fully seperate the aluminum (3) after the bauxite is grinded (4). The next step is filteration (16) to seperate (15) any other substances that went through. After that process (1) of assurance (5), it is the liquified (17) for the next step (6). the next step is to process it to a powdered (20) form. The color is a white (21) color. The chemical/substance (2) that is used now to seperate the aluminum + oxygen (26) by means of  electricity (27). The aluminum is now bright (31), silvery (32), and comes in many forms (33)
