bentonite iron ore pelletization

Review of Organic Binders for Iron Ore Agglomeration

May 22, 2013 agglomeration and concluded that inorganic bentonite clay "is still the dominant binder", although it is expensive and is not silicafree (Eisele and Kawatra, 2003). Organic binders have significant potential as a bentonite replacement as evidenced by their successful use in the U.S. iron ore pellet market.

Characterization of iron ore pellets with dextrin added IOPscience

Abstract: In the present work, Dextrin is used as a binder for iron ore pelletization, as it's free from Silica and Alumina. Green pellets were prepared by mixing of iron ore particles (. 75 µm) with varying binder percentage (1 wt. % bentonite, 0.5 and 1 wt. % of dextrin) separately. The green pellets were first dried in air for 24 h
