Iron ore concentrate is received from the concentrating operations where it is ground in one of 11 ball mills. The ground concentrate is then mixed with certain additives and formed into balls 9.5 mm to 12.5 mm in diameter that are dried and then fired. The plant produces a variety of pellet products – standard acid pellets; low silica acid ...

Powdery iron ore includes the concentrate and natural rich ore produced by fine grinding separation. Iron ore powder agglomeration is the basis for blast furnace ironmaking and is the processing work in between ore crushing, ore grinding separation, and steelmaking. Its purpose is to provide high-quality furnace burden for steelmaking.
