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

The smelting process is essentially the removal of the oxygen that is combined with a metal in its ore to leave the metal on its own The means of doing this is to expose the ore to a reducing gas at high temperature The metals of antiquity can each combine with different proportions of oxygen to form more than one specific compound
