Aluminum is an abundant metal
with many uses. Aluminum comes from an ore called Bauxite. Bauxite looks
like clay and contains aluminum and several other substances. workmen extract
these other substances then grind the Bauxite. They then put the Bauxite
in pressurized tanks. In the tanks the other substances form a mass, this
mass is then removed by use of filters. All that is left is a liquid that
they process several times to create a powdery white chemical, this is
alumina. Alumina is a mixture of aluminum and oxygen that is seperated
using electricity. The final product is a shinny and light metal that is
silvery. This metal, aluminum, comes in many forms. |
