A Novel Approach for Utilization of Ultra‐Fines Iron Ore in ...

Abstract. The current study presents a novel approach for the utilization of ultra‐fines iron ore −0.2 mm in sintering process through its conversion into mini‐pellets 4–9 mm . The mini‐pellets were composed of ultra‐fine iron ore and calcium hydrate while coke fines were used as a coating layer. One part of mini‐pellets was cured with CO2to improve the strength of green pellets while another part was kept uncured.

Iron Ore Sinter - an overview ScienceDirect Topics

The effect of iron ore characteristics on sintering is mainly through their impact on the granulation and densifi ion processes. With the rapid change in iron ore supplies and composition, steel mills now have to adjust the composition of the ore mixture to their sinter plants more frequently than ever before. Hence, different scales of test methods have been developed to help sinter plants evaluate new ore types and ore blends in order to optimize their ore mixtures.
