Iron ore pelletization

Iron ore lump, sinter, and pellets comprise the main burden of modern blast furnaces. However, sinter and pellets are now the dominant blast furnace burden, because the natural lump supply has declined dramatically due to depletion of the world's high-grade competent iron ore resources. In addition, more iron ore concentrates are being …

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.
