Aluminum is a very useful and
abundant metal. It contains several substances taken from the ore Bauxite
from aluminum is also derived. To form aluminum, the Bauxite is ground
and put into pressurized tanks until it forms a mass. The mass is then
removed and filtered, leaving only a liquid. Several other processes are
applied; finally yielding a white, powdery chemical called "alumina". Alumina
contains aluminum and oxygen. In order to extract the aluminum from the
chemical, workmen use electricity to eventually produce the light metal.
The metal comes in several forms, however it is always bright with a silvery
luster. |
