Pelletizing, in ironmaking, is a process used to agglomerate iron ore concentrates with a granulometry <150 µm and low concentration of impurities.Iron ore concentrates are mixed with water, bentonite, and hydrated lime (cold agglomeration) and are treated in a rotary disk to form round agglomerates (green pellets) with sizes comprised within 10 and 20 mm in diameter.
Emission Optimized Sintering (EOS®) for lower costs Iron ore sintering creates substantial off-gas volumes, and treating these in order to meet increasingly stringent environmental standards is expensive. EOS® uses recycling technology to reduce off-gas volumes by 40 to 50 %, resulting in smaller secondary gas treatment systems. This means:
