Ferrous metallurgy, in particular the process of pelletizing iron ore concentrates, is one of the main consumers of bentonite clays. The problem with the bentonite binder is well known, and is the increase in silica content (the main harmful impurity) in the roasted pellets as a result of its use. This predetermines long-term …
In the ironmaking process, the addition of an organic binder to replace a portion of bentonite has the potential to improve the performance of pellets. The …
Green iron ore pellets are nearly spherical agglomerates produced in balling discs or drums from a mixture of fine iron ore concentrate, agglomerating agents and water [1].
