ore sintering - an overview | sciencedirect topics

Apr 02, 2010 · Original purpose of the iron-ore sintering process is to agglomerate fine ores into lump burdens for blast furnace (BF). Since sintering conditions, e.g., kinds of ores and used fluxing materials, and pregranulation processes, strongly affect the metallurgical properties of the produced sinter, many researches and developments on the sintering process have been made in order to achieve a stable …… Read more

a novelapproach for utilization of ultra‐fines iron ore

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 CO 2 to improve the strength of green pellets while another part was kept …… Read more

Sintering is the most extensively used and economic agglomeration process to prepare iron ore fines for blast furnace use. Granulation is the most critical factor controlling iron ore sintering process, as it improves sinter mix permeability. Currently, sinter plants are receiving significant proportion (up to 40%) of − 150 μm micro-fines in iron ore fines, which makes sintering difficult… Read more
