Aluminum is an abundant metal. It has many uses in today's world. Many of us have no clue were it comes from or how we get it. Well, in the next few paragraphs I will explain the process that is followed to create this useful metal. Aluminum comes from the ore bauxite. This ore has a clay like appearence, and contains several other substances besides aluminum. In order make aluminum workmen remove the various substances that are not aluminum, from the bauxite. To remove the aluminum the bauxite is ground up and placed into tanks. When these tanks are preasureized the foreign substances form a mass. The mass is then removed by filters, and the remaining product is a liquid. After several other processes, a white, powdery chemical is yielded. This chemical alumina is a mixture that contains aluminum, and oxygen. The aluminum is then removed from the oxygen useing electricity. The final product is a light metal, with a bright, silvery luster. This process allows us to use this metal in many ways. |
