the percentage of iron ore pellets in blast furnaces has increased due to its uniform size, good reducibility, and high tumbler index. Pelletizing is energy-intensive and emits considerable CO 2. Around 20% of CO 2 emissions during pellet making come from uxes. In the present work, the authors established a novel CO 2

THE POTENTIAL OF PELLETIZING FOR IRON ORE PROCESSING The technology of pelletizing iron ore has been used for decades. The basic principles are the same, but there ... furnace converter route was still evident. However, the latest efforts to reduce global CO2 emissions show a trend reversal. From 2017 to 2018 alone, global …

Benefits of Pelletized Iron Ore. In addition to the factors listed above, iron ore pellets also offer a number of benefits to steel producers, some of which include: Improved productivity per cubic meter of blast furnace 1. …

technology installed in a pelletizing disc or drum. Based on the measurement data the plant's process control system can optimize the rotation speed of pelletizing discs/drums and the feed rate in real time. The performance of an induration furnace is heavily determined by the gas permeability in the pellet bed.

Abstract. The iron and steel manufacturing sector directly accounts for 7-9% of global CO 2 emissions. Raw material preparation, such as iron ore sintering, pelletizing, and cock making, is the major CO 2 emitter. As climate change becomes a bigger concern, steel manufacturers need to lower CO 2 emissions without hindering efficiency or increasing …

In the pelletizing process, iron ore concentrate is rolled into balls (pellets) and hardened through thermal treatment in an induration furnace. The induration furnace is the primary source of emissions from this sector of sulfur dioxide (SO 2 ), inhalable particles with a diameter of 2.5 microns or less (PM 2.5 ), and oxides of nitrogen (NO x );
