Abstract. Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. Owing to the depleting reserves of traditional high grade iron ore, there have been considerable changes in iron ore resources available throughout the world, especially in steel mills in East Asia.

Furthermore, the reduction rate of sinter and iron ore pellets begins to resemble each other at higher temperatures. 1 Introduction. A blast furnace (BF) is the most common process for hot metal production in the world. The BF is charged with metallurgical coke and iron-bearing materials separately, which leads to a layered structure.

Based on the particle size, iron ores are classified as iron ore fines (<10 mm) or iron ore lump (6.3–31.5 mm); iron ore fines are first processed in a sinter plant, while lump ores can be charged into the blast furnace (BF) directly. Iron ore lump is the lowest cost iron bearing material for the BF burden.
