Aluminum is a very distinct
metal. It is abundant and has many uses. Aluminum comes from an ore called
Bauxite. This ore has the appearance of clay. Bauxite also contains other
substances which are not needed to produce aluminum. These substances must
be removed. Workmen seperate them by grinding the ore. After grinding the
mix is put into pressure tanks where the unused substances are removed.
A liquid remains in the tank which is extracted by using filters. This
liquid then goes through several other processes until a white, powdery
chemical is yielded. The chemical produced is alumina. It is a mixture
which contains aluminum and oxygen. The final product of this process
is a metal. The metal called alumina has a bright, silvery luster. It is
also a light metal. The metal can be found in many forms and is very useful |
