The metal aluminum has many
uses and is abundant. It comes from buaxite ore that looks like clay, and
contains aluminum. Buaxite also contains several other substances. Workman
grind the buaxite, and put it in pressurized tanks. The other substances
then form a mass, which is removed with filters. After filtering a liquid
remains, then it is put through several other processes. When finished
it yields a chemical which contains aluminum and oxygen. Workmen then use
electricity to seperate the aluminum and oxygen. The finished product is
a light metal with a silvery bright luster. This metal can be found in
many different forms. |
