| Aluminum is an abundant metal
that comes from bauxite. which is an ore that looks like clay and also
contains aluminum. Bauxite also contains many other substances. Workmen
extract these substance when they grind the Bauxite. They put it in tanks,
then add pressure, and the substances form a mass. The mass is then removed
with filters and the liquid remains. After that it goes through many other
processes until it finally yields a chemical. The chemical is powdery and
white. The chemical is alumina and is a mixture of aluminum and oxygen.
Workmen then separate them and use them for electricity. After this it
becomes a metal. The metal is a silvery bright luster and comes in many
forms. |
