Iron Ore Pelletizing Process: An Overview

Bentonite, an inorganic binder, has been the main binder used in the iron ore pelletizing process since the beginning of pellet production in the 1950s. Bentonite promotes the forma- tion of ceramic bridges between particles, which can minimize the number of pellets that collapse during firing.

Pellet feed grinding by HPGR ScienceDirect

Mar 15, 2015 Pellet feed material generally results from fine grinding to achieve a liberation size roughly between 20 μm and 150 μm. Following this, beneficiation is applied to generate concentrate grades of 65–69% Fe, by gravity separation, magnetic separation or flotation, or combinations thereof.

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
