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 …

ABSTRACT The behavior of iron ore pellet binders is complex. Any pellet binder is subject to a handful of practical requirements: that it be readily dispersed through a pellet, that it effectively controls the movement of water within the pellet, and that it contributes to the inter-particle bonding within the pellet. Meeting these requirements …
