| A type of metal called aluminum
is made through many processes. Aluminum is an abundant source of metal
and is used in various forms. Aluminum is processed from bauxite which
is an ore. Bauxite has the features of clay and contains many other substances.
The first step in the production is the removal of the other substances.
Workmen grind the bauxite and put it in pressurized tanks. Those other
substances form a mass, removal of the mass is done with filters. A liquid
remains in the tanks and is put through many other processes where it yields
a chemical, a powdery-white chemical; alumina. Alumina contains aluminum
and oxygen. Electricity is then used to separate aluminum from the oxygen.
FInally a metal is formed, lightweight and a bright luster. Aluminum has
been produced and comes in many forms. |
