Reduction Kinetics of iron ore pellets and effect of binders

Reaction kinetics of iron ore reduction deals with the rate at which iron oxide is converted to metallic iron by removal of oxygen. The rate at which the ore is reduced influences the production rate, which ultimately determines the economic feasibility and competitiveness of the process technology involved.Thus the reaction rate in DR process is of prime importance.

The iron ore importance in Direct Reduction

One possibility is through concentration and pelletizing of iron ore, to eliminate as much as possible excess of gangue, to increase the total iron content. The other possibility is to adjust the composition in the EAF or in the ladle after the DRI is melted. In this regard, the economy of the overall steelmaking process (DR-EAF) is an important condition for the adjustment of the ore chemical ...
