| Aluminum is a abundant metal
that comes from bauxite. Bauxite is a ore that looks like clay and contains
aluminum along with many other substances. Workmen extract these other
substances by grinding the bauxite and putting it in pressurized tanks.
The workers remove the unwanted materials with filters as a result a liquid
remains. They put the liquid through more processes which yeilds a powdery
white chemical. The chemical is alumina which is a mixture of aluminum
and oxygen. Workmen use electricity to separate the aluminum from the oxygen.
They finally produce a light, bright, silvery metal that comes in many
forms. |
