Pig iron is the basis of a majority of steel production. A majority of steel produced in the world is created through pig iron production. Sponge iron. Removing oxygen from the ore by a natural process produces a relatively small percentage of steels in the world. This process uses less energy and is a natural chemical reaction method.

Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) into iron by a reducing gas or elemental carbon produced from natural gas or coal.Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting
2. PRODUCTION OF IRON AND STEEL POWDERS 8 2.3 The Höganäs Sponge Iron Process The Höganäs sponge iron process, is essentially a chemical process in which finely divided iron ore is being reduced with coke breeze yielding a spongy mass of solid metallic iron, which can readily be comminuted to iron powder. The iron ore used at
Malcolm Tatum Sponge iron is created from iron ore. Sometimes known as direct-reduced iron, sponge iron is a product that is produced using iron ore.The iron ore is often in the form of pellets or lumps, and is subjected to a reduction process that is created by the use of a reducing gas that emits from coal or a natural gas source.
Iron ore crushing is not required since sized material has to be purchased. Iron ore of size 5 mm to 20 mm is being used for the production of Sponge iron. Iron ore is being fed to the Ground hopper, from where it conveyed to the Screen with the help of Vibro Feeder, where Oversize i.e. + 20 mm and Undersize i.e. 5
In the Direct Reduced Iron (DRI) plant, production of sponge iron using a solid reductant involves reducing iron ore (lumps/pellets) with a carbonaceous material such as coal. The reduction is carried out in a rotary kiln (which is inclined and rotates at a pre-determined range of speeds) at a stipulated temperature (850°C -1,500°C).

4.1.2 Iron Ore Beneficiation Iron ore occurs naturally in a variety of forms, from sand-like iron fines to solid rock masses. Crude ore, or ore mined in the natural state, seldom occurs in a pure state and requires some form of beneficiation. Crude ore is commonly mixed with other minerals (gangue), which reduce the iron content.
