Introduction to Iron ore Pellets and Pelletizing processes ...

At 800 deg C, the FeO of the magnetite iron ore gets converted into Fe2O3 in an exothermic reaction. The liberated heat hardens the green balls which is helpful to withstand the tumbling impact due to the rotation of the rotary kiln. A circular cooler is used for cooling of the fired pellets. Flowsheet of grate kiln process is given at Fig 3.

01/09/2020  It is because the diffusion bonding of magnetite pellets (which enhance CCS of the pellet) is more during induration than that of the hematite ore pellet at low temperature. Because of this, in hematite ore pelletization, coke fines are required to give the in-situ heat for maintaining the compressive strength of the pellet. From the experimental data, it was observed that around 2% of the ...

does magnetite ncentrate need to be pelleted

how toconvert magnetite ore into pellets. Pellet production with magnetite concentrates was given more predominance due to the heat liberation during magnetite oxidation to hematite However, due to the absence of any exothermic reaction and diffusion bonding, hematite ore pellets require very high induration temperature (>1300°C) which makes the process highly energy intensive

Production of Pig Iron from Magnetite Ore–Coal Composite ...

Magnetite ore–coal composite pellets with about 10, 15 and 20mm diameter were rapidly smelted to produce pig iron by microwave heating in N 2 gas. A microwave generator with 5kW maximum power at 2.45GHz was employed. Carbon content in pig iron was about 2mass% near the liquidus line in the Fe–C system. Slag was easily separated from pig iron. By XRD analysis it is realized that the ...
