The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron
Steel production & environmental impact
Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 92-94% iron and 3-5% carbon with smaller amounts of other elements. Pig iron has only limited uses, and most of this iron goes on to a steel mill where it is converted into various

Steel making experience in the use of Nigerian Iron Ore at
The production of steel from the locally available Itakpe Iron Ore in Nigeria was achieved in the Delta Steel Direct Reduction-Electric Arc Furnace Plant. The ore was originally thought to be unsuitable for use in the direct reduction process due to its low total iron content, less than 64% and high gangue content which was in excess of 4% and above the maximum acceptable limit of 3.5%.
Steel Production American Iron and Steel Institute
The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal is a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of
Iron Native Mineral Properties, Uses and Occurrence
Uses Area. Near the producer of iron produced in the world is used in steel making. Because It alone is the successful strong depot. Tungsten, manganese, nickel, vanadium, chrome etc. It is used in many areas such as construction and automobile. Powder iron: used in metallurgy products, magnets, high frequency nuclei, automobile parts, catalysts.
