Iron is the backbone of the world we have built around us and it is the basic ingredient of steel (iron plus carbon). Iron is a very useful metal because it can be mixed with other metals to make a whole variety of alloys which are even stronger and dont rust easily and can be shaped into products from cars to pins, household appliances to buildings, bridges to railways, food cans to tools.
Limonite, a compound of iron, oxygen, and water FeO(OH) nH 2 O Fe 2 O 3 nH 2 O, is a yellowbrown to dark-brown or black, seemingly noncrystalline mineral.
