As shown in Figure 14.1, iron ore sintering is carried out in three stages raw material .These plants use iron carbide, an iron ore that contains 6 carbon rather than 1.5-1.8 of regular iron ore . The additional carbon ignites in the presence of oxygen and contributes heat to the iron melting process, reducing energy requirements Ritt, 1996.Mill scale is one of waste materials which is produced as a result of hot rolling of steel in all steel companies. On the other hand, mill scale is considered a rich iron source with minimum impurities.Sep 29, 2014 Sludge is generated at the clarifier of the water treatment plant. These dusts and sludges are rich in iron Fe and contain good amount of lime CaO, magnesia MgO and carbon C. These materials are very good materials for recycling back in sinter making. These materials are either blended with iron ore fines or briquetted for recycling.Mar 01, 2018 The mill scale is mainly composed of iron oxides. Total iron content in the mill scale could be up to 7075. Therefore, the mill scale can be an excellent alternate iron-bearing feedstock for ironmaking and steelmaking.

Total generation of mill scale at JSWSL is around 150 tday and contains 6070FeO and 3035Fe 2 O 3.To recover the iron, the mill scale must be smelted in a blast furnace or other reduction furnace however, it is usually too fine to use without previous agglomeration such as via pellet or sinter mix.2005. A. Mill scale consists primarily of magnetite, Fe 3 O 4, of characteristic blue-gray steely color. An extremely thin outer film of hematite, Fe 2 O 3, is invisible to the naked eye. The inner portion of the magnetite contains fine metal grains and sometimes, residual black FeO see below, which contribute to the roughness of descaled metal.Chilled iron surfaces are used for resisting abrasion. White iron is also the starting point for the production of malleable iron. 3.
