Aluminum is an abundant metal
with many uses. It is made from an ore named Bauxite. Bauxite looks like
clay and has many substances in it, but to get the aluminum out of it workers
have to put it through a process. In the process they put it in pressurized
tanks, remove all the other substances, filter the liquid, then put it
through a few more steps. When the process is complete they have a chemical
mixture named alumina. In this mixture is oxygen and aluminum. To get the
aluminum out they use electricity and then it forms a metal. The metal
is light, has a bright silvery luster, and comes in many forms. |
