Pellet (Iron ore) - Mining Fundamentals

Iron ore pellets are marble-sized balls of iron ore that are fused with clay for transportation and used in steel manufacture. The process of making pellets from iron ore is called pelletizing. The manufacture of steel from low-grade iron ore involves processes like mining, crushing, separating, concentrating, mixing, pelletizing, and shipping.
