| Aluminum is an abundant metal
that has many uses. This metal comes from bauxite which is ore that looks
like clay. Bauxite contains aluminum along with several other substances.
Workmen extract these substances by first grinding them and then putting
them in a pressurized tank. The substances remaining form a mas which is
then filtered and a liquid remains. After several other processes it yields
a white, powdery chemical. The chemical remaining is alumina that contains
aluminum and oxygen. The oxygen is seperate by electricity. Finally, a
metal with light and luster that is bright and silvery is formed |
