Sintering of the pellets of Egyptian iron ore with lime and reduction of its via hydrogen

This investigation studied the effect of lime addition to the Egyptian iron ore raw material on the physicochemical properties of its pellets in green and indurate form. Also the effect of this addition on the degree of reduction was studied. The results indicated that the addition of (2-8%) lime decrease the mechanical properties of the both green and indurate pellets. Also the reduction of these pellets via hydrogen was studied and the model of reduction was put in this paper.
