Aluminum is an abundant metal
with a variety of uses. It comes from bauxite, which is an ore that looks
like clay. Bauxite contains aluminum as well as many other substances.
Workmen must first extract the substances from the bauxite and put it into
pressured tanks. After this step a liquid remains which is put through
many processes until it finally yeilds a chemical. The chemical is a white
powdery mixture called alumina which contains aluminum. The alumina also
contains oxygen. Workmen must then work to seperate the oxygen and the
aluminum by using electricity. After this they finally produce a metal.
The metal, or aluminum in its final form, is light in weight and very shiny.
It is then shipped out to different companies and manufacturers where it
will then be formed into different materials. |
