Aluminum is an abundant metal
that has many uses. It comes from a clay like ore called Bauxite. The workmen
grind the Bauxite after they have extracted the other substances and put
them into a pressure tank where they form a mass. Then they use filters
to remove the mass which leaves a liquid. This has to go through many other
processes to form a white and powdery chemical called Alumina.
Alumina contains aluminum and
oxygen, which workmen seperate by electricity. They finally produce a bright
and silvery luster metal that comes in many forms and is light to use. |
