Diffusion Bonding Pellet Iron Ore

Iron Ore Pelletizing Process: An Overview | IntechOpen

The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process ...

Replacement of bentonite in hematite ore pelletisation ...

Replacement of bentonite in hematite ore pelletisation using a combination of sodium lignosulphonate and copper smelting slag A. Ammasi and J. Pal* Bentonite is the most common binder used in iron ore pelletisation owing to its good bonding properties in green and dry pellets at both ambient and elevated temperatures. However, due to

Development of hematite ore pellet utilizing mill scale ...

While mill scale provides exothermic heat of oxidation of FeO and Fe3O4 in it and enhance the diffusion bonding, slime provides good green bonding property to the pellet. Therefore, in this study a good quality pellet was developed by the combined mixing of these two wastes in hematite ore without much increase in gangue content.

Carbon as in situ energy source in induration of hematite ...

AbstractFuel consumption during high temperature induration is one of the principal reasons for the cost intensiveness of the iron ore pelletisation process. While magnetite ore is oxidised to hematite during induration at high temperature and provides internal heat energy to the pellet, there is hardly any internal heat generation. Furthermore, magnetite is prone to form diffusion bonds at ...
