Iron Ore Pellet - an overview ScienceDirect Topics

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. The fine particles are reconstituted into moist pellets about 1 cm in diameter, and then indurated by heating to temperatures approaching 1300 °C. This is
