KOBELCO Pelletizing Process

Pellets are made from iron ore that is finer than that used for sintered ore. The ore fine is formed into spheroids, called green balls, approximately 12mm in diameter. The green balls are fired into iron ore. His process involved grinding taconite to remove gangues and upgrading the iron ore (i.e., an ore beneficiation process). The

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
