Iron Ore Pelletization: Part I. Fundamentals | Semantic Scholar
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 …
Iron Ore Pelletization: Part II. Inorganic Binders
ABSTRACT The addition of pellet binders often represents a compromise between the pellet grade and quality measures as strength, reducibility, and dustiness. Each inorganic compound present within the pellet plays a specific role in each aspect of creating a high-quality pellet. This review seeks to clarify the roles of both binders and …
