Iron has a chemical formula (Fe), and it is one of the most common elements in the world and forms 5% of the crust of the Earth. It ranks the fourth among the common elements after Oxygen, Silicon, …
Iron is too reactive to exist alone, so it only occurs naturally in the Earth's crust as iron ores, such as hematite, magnetite, and siderite. One of iron's identifying characteristics is that it is strongly magnetic. Exposed to a strong magnetic field, any piece of iron can be magnetized.
Iron ore is the source of primary iron for the world's iron and steel industries. It is therefore essential for the production of steel, which in turn is essential to maintain a strong industrial base. Almost all (98%) iron ore is used in steelmaking. Iron ore is mined in about 50 …
