| Aluminum is an abundant metal
with many uses. This metal is found in the ore Bauxite, which resembles
clay. Bauxite contains aluminum along with several other substances. These
substances can be extracted through a long process. The bauxite is grinded
and put into pressurized tanks. The other substances form a mass, which
is then filtered producing a liquid. After the liquid is put through several
other processes it yields a white, powdery chemical called alumina. Alumina
is a mixture that contains aluminum and oxygen. The aluminum can be separated
from the oxygen through the use of electricity, which produces a light
metal with a bright, silvery luster that comes in many forms. |
