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.

Direct reduced iron plant - Global Energy Monitor
2021-7-12 Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, and/or fines) into iron with a sponge-like exterior, without melting. The heart of the direct reduction is the shaft furnace, which is filled from the top with lump ore and pellets. DRI production turns iron ore into iron using gaseous reducing agents such as ...
