Iron Ore Pelletization: Part I. Fundamentals

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 leads to the formation of strong …
