Iron Ore Agglomeration Technologies IntechOpen

Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron

Iron Ore Pellet - an overview ScienceDirect Topics

1.1.3.2.1.2 Iron-Bearing Materials. Ore fines and iron concentrates make the main part of the sinter mix. The grain size of ore fines and concentrates is typically 0–8 and 0–3 mm, respectively. Grains smaller than 0.1 mm are not desired because they reduce the gas permeability of the bed and thus decrease the sintering efficiency.

Study on Application of Iron Ore Fine in Pelletizing

Pellet production requires iron ore concentrates have fine particle size, high specific surface area and good balling performance, so iron ore concentrates appropriate for pelletizing is limited compared to sintering.
