Iron Ore Smelting Process - Bright Hub Engineering
Here the ore is put into a blast furnace along with limestone and coke and subjected to hot air blasting and heat which converts the ore to molten iron. This is tapped from the bottom of the furnace into molds known as pigs and allowed to solidify into pig iron. This pig iron is converted to wrought iron or processed into steel by several methods.
