Aluminum is an abundant metal
with many uses. Aluminum is one of the many substances able to be extracted
from the clayish boxite. Workmen are able to remove the aluminum from the
boxite by placing it into pressurized tanks. This causes all the other
substances to form a mass. They remove and filter the mass, until only
a liquid remains. They put the liquid through several processes, to yield
a white, powdery chemical called alumina. The alumina contains both aluminum
and oxygen, which are seperated electrically, by the workmen. They finally
use the aluminum to produce a light, bright, silver, lusterous metal, which
comes in many forms. |
