    Introduction to Iron Ore and Steel Smelting ProcessingThe Mining of Iron OreIron Ore Smelting Process Using Modern Blast Furnaces.Converting Pig Iron to Wrought Iron and Steel.Iron ore is obtained in the conventional method of open cast or underground mining and conveying the ore to the surface preparation are where it is crushed, washed, and transported to the smelter. 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 ste
