Effects of bentonite fiber formation in iron ore

2002-7-1  1.. IntroductionIron ore pelletization plants in the United States used approximately 612,000 metric tons of bentonite as a binder to produce iron ore concentrate pellets in 2000 (Virta, 2001).It is a major cost item, with individual plants spending US$3–5 million annually for bentonite.

Characterization of Humic Acid Modified Bentonite Binder

Anew kind of iron ore pellet binder named humic acid modifying bentonite (HA-MB) has been developed by the author’s group, which has the advantages of both organic HA and inorganic bentonite. The green pellet strength can be obviously improved by using the HA-MB binder.
