Iron

We treat iron as a mineral. Iron is the most important metal in the modem world. We get iron from two main ores, hematite and magnetite.

These are rich in iron compounds. The iron ores are processed in steel plants to extract and prepare different forms of iron like pure iron, wrought iron, cast iron, steel, stainless steel etc. Pure iron is a silvery white soft metal. It becomes rusty in presence of air and moisture and appears reddish brown in color. Iron absorbs heat very quickly. It is also a good conductor of electricity.

The different uses of iron are discussed here. Pure iron is mixed with other materials for hardening before it is used in different industries. Wrought iron is used to prepare chains, wires and modern furnitures and staircases. Manhole covers, bodies of tube-wells and pump sets are made of cast iron. Steel is used in making railway tracks, building materials, rods, pipes and wires. Utensils, surgical instruments, razors, etc., are prepared by stainless steel.
