    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
  • Iron Ore HowStuffWorks

    Smelting involves heating up ore until the metal becomes spongy and the chemical compounds in the ore begin to break down. Most important, it releases oxygen from the iron ore, which makes up a high percentage of common iron ores. The most primitive facility used to smelt iron is a bloomery.

    Of the seven metals known in antiquity, only gold occurs regularly in native form in the natural environment. The others – copper, lead, silver, tin, iron and mercury – occur primarily as minerals, though copper is occasionally found in its native state in commercially significant quantities. These minerals are primarily carbonates, sulfides, or oxides of the metal, mixed with other components such as silica and alumina. Roastingthe carbonate and sulfide minerals in air converts them to oxides. The oxides, in turn, are smel

Instead the product of the smelt is a spongy mass of iron and slag known as a ‘bloom’. This then needs to be consolidated by hammering while the bloom is at a (white) welding heat. In doing so, the slags trapped in the bloom are squeezed out and the gaps are
