How is Iron Refed From the Ore? - novateus

Iron was origally known by its Lat name”Ferrum” from which its chemical symbol is derived. Iron ore is converted to various types of iron through many processes. The most common process is the use of Blast furnace to produce pig iron which is about 92-94% iron and 3-5% carbon with smaller amounts of other elements.
