Iron (FE) ore deposits are approximately 0.24-0.63 inches to be used in a blast furnace. Pelletizing combines the addition of other additives to form raw pellets into spheres. Balls of iron are fired in a kiln to sinter the particles into a hardened form. Iron ore pellets restrict airflow thus resulting in a superior product fit for a kiln.
