Iron ore pelletizing is an essential industrial process that transforms powdery iron ore into uniform, robust pellets, serving as a premium feedstock for blast furnaces and direct reduction reactors.

In general, pelletization of iron ore is a process where the feed is a mixture of high-grade hematite/magnetite ore mixed with binder and coke breeze as additives to form pellets for the production of iron and steel [5]. Such types of initiatives can eradicate the crises of high-grade iron ore demand as pellet feed material as well as support ...

The pelletization process is an established and economical route for enhanced utilization of the beneficiated micro-fines. The pellet feed is produced by mixing iron ore fines (-150 µm) with additives and a binder to meet the pellet quality requirements. The feed is then formed into spherical-shaped green pellets of 9–16 mm in diameter.

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 …
