Water and other volatile impurities like sulphur and carbonates are removed by the process of Concentration. The concentrated ore is blended with limestone (CaCO3) and Coke and fed into blast furnace from the top.
Iron ores consist of oxygen and iron atoms bonded together into molecules. To convert it to metallic iron it must be smelted or sent through a direct reduction process to remove the oxygen. Oxygen-iron bonds are strong, and to remove the iron from the oxygen, a stronger elemental bond must be presented to attach to the oxygen. Carbon is used because the strength of a carbon-oxygen bond is greater than that of the iron-oxygen bond, at high temperatures. Thus, the iron ore must be powdered and mixed with coke, to be bu…Reduction roast and magnetic separation of oxidized iron,,01-06-1998· The principle of the process consists of converting the iron bearing minerals into the magnetic state so that magnetic separation can be employed to concentrate iron from the ore .
