Abstract

The present invention discloses a new process for the improvement of reducibility of iron ore pellets comprising the steps of i) preparing a raw material mixture which contain metallic Ni powder; ii) pelletizing the said mixture obtained; iii) burning the said raw pellets and iv) reducing the said burnt pellets under reducing conditions with presence of CH4.
