The document discusses sinter making technology used in iron ore mining. It describes how iron ore fines generated during mining cannot be directly charged in blast furnaces due to size restrictions. Sintering is used to agglomerate the fines into a porous mass that meets size requirements. The key steps in sinter making include: 1) raw ...

6. Occurrence of Iron Iron is very reactive and is found in nature in form of its oxides, carbonates and sulphates. The main ores are: i) Haematite (Fe2O3) ii) Magnetite (Fe3O4) iii) Iron Pyrites (FeS2) o The main iron ore is Haematite (iron (III) oxide - Fe2O3). o The iron ore contains impurities, mainly silica (silicon dioxide). o Since iron is below carbon in the reactivity …

World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. 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 and steel in a blast furnace.

Fig 1 Iron ore sinter. Types of sinter. Sinters are classified into acid sinter, self-fluxing sinter, and super fluxed sinter. Self-fluxing sinter has sufficient content of CaO (lime) in it which is required to flux its acid components (SiO2, and Al2O3). Super-fluxed sinter has additional content of CaO for fluxing of the acid components ...

18. Fine iron ore is preheated and reduced to fine direct reduced iron (DRI) in a three or four stage fluidized bed reactor system. The fine DRI will be compacted and then charged in the form of hot compacted iron (HCI) into the melter gasifier. The charged HCI is subsequently reduced to metallic iron and melted. The generated FINEX export gas is a highly valuable …

The size of iron ore affects the sintering properties. An increase in the size of iron ore promotes the productivity of sinter, but can reduce the tumbler strength slightly and save a little coke. The mineralogy of sinter can more easily be predicted from its chemical composition than its physical and chemical properties.
