Reduction Kinetics of Fluxed Iron Ore Pellets Made of Coarse Iron Ore Particles

steel research international, Volume 96, Issue 4, April 2025.
The present work evaluates possibility of using relatively coarser iron ore particles for iron making via agglomeration. The motivation is to reduce the energy consumption in milling of the iron ore. The results show that pellets made with coarser iron ore particles have improved reduction behavior and kinetics.

Characterisation of the Physical and Metallurgical Properties of Natural Iron Ore for Iron Production

International Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012
The blast furnace is still the dominant form of iron production, but over the years, direct reduction methods have increased due to a number of reasons. Overall, iron production methods have optimal requirements with respect to the feed materials especially iron ore.

A Simplified Approach Based on Cellular Automata for Describing Direct Reduced Iron Production in Different Reducing Conditions

steel research international, Volume 95, Issue 3, March 2024.
A fast cellular automata model with low‐computational burden is developed to tackle the direct reduced iron production process under different conditions as a feasible tool for in‐line control of the reduction process. The robustness of the model is confirmed through comparison with industrial data of the final reduced product and that foreseen by the ...
