Pellet (Iron ore) - Mining Fundamentals

The reason why iron ore is preferred in the form of pellets, rather than as particles, is that pellets allow better air flow in the furnace, thereby ensuring better smelting of ore. Pelletizing During the process of pelletizing, the non-agglomerated iron ores are mixed together with the additives.
