magnetite ore fines used in sinter making


Thermodynamic and Mineralogical Aspects of Injecting LPG ...

Iron ore sinter is an agglomerate of iron ore fines, produced at an elevated temperature of about 1300 °C [1, 2]. A slag bond generated by fusing fluxes such as limestone and dolomite, holds the iron ore particles together . The most commonly used source of heat is coke fines, at a rate of 58 kg/ton of sinter.
