Sinter and pellet are both agglomerated forms of iron ore used in the iron and steel industry, but they differ significantly in their production processes, physical properties, and applications. Sinter is produced by sintering, a process that involves heating fine iron ore particles with fluxes and other materials to form a porous mass.

This process generates iron ore filter cake which needs to be pelletized to be used in the steel making process. Also during the processing of high grade iron ores which don't need beneficiated, fines which are generated can be pelletized and used instead of being disposed of. Iron Ore Pellets are formed from beneficiated or run of mine iron ...

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.
