| Aluminum is a metal that is
abundant and has many uses. It comes from bauxite. Bauxite is an ore that
looks like clay and contains aluminum along with several other substances.
Workmen extract these other substances from the bauxite, and then grind
bauxite and put it in tanks with pressure. The other substances form a
mass. They use filters to remove mass and a liquid remains. They put it
through several other processes and it finally yields a chemical. The chemical
is white powdery and is alumina. Its a mixture that contains aluminum and
oxygen. Workmen use electricity to seperate aluminum from oxygen to produce
metal. The metal is silvery, has bright luster, is light and comes in many
forms. |
