Aluminum is a metal that has
many uses and is abundant. It comes from bauxite which is an ore and it
looks like clay. Bauxite contains aluminum and several other substances.
Workmen extract these substances by grinding it and putting the ground
bauxite into pressurized tanks. They remove the remaining mass and put
it through several filters to produce a liquid which is then put through
several processes until it yields a chemical. This chemical is a white
powder called alumina that contains aluminum and oxygen. The workmen use
electricity to seperate the aluminum from the oxygen to produce a metal.
This metal is light with a bright silvery luster that comes in many forms. |
