grinding size iron ore pellets

Iron Ore Pellet an overview ScienceDirect Topics. Shaft furnaces use pellets (produced in the same way as pellets for the BF), or lump ore. Raw material for pellets is produced by crushing and grinding low-grade iron ores—typically of the taconite class and finer than 325 mesh (0.044 mm)—and magnetically separating the iron oxide (magnetite, Fe 3 O 4) from the siliceous gangue.
