Country having highest reserve of iron ore production
Answers
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, and Aluminum. Iron forms a critical part of modern civilization and its use dates back to thousands of years. It was only around the 14th Century when its use became widespread as smelting furnaces increasingly began to replace the older forges. Iron ore occurs in the form of rock from which the metallic iron is the final product. The bulk of these rocks are either Hematite or Magnetite, and it makes almost 98% of the iron ore produced worldwide that goes into making steel. Much of the iron ore mined are oxide compounds of Magnetite (Fe3O4), Hematite (Fe2O3) Goethite (Fe2O3SH2O), and Limonite. Magnetite is composed of 72% iron, Hematite is 70% iron, Goethite is 63% iron, and Limonite is 60% iron.
