Binding Mechanism in Green Iron Ore Pellets with an Organic Binder
ABSTRACT Organic binders have been used as alternative to bentonite in the iron ore pelletizing process mainly because it burns without leaving residue in the pellet. There are two main types of organic binders, those based on cellulose and those based on polyacrylamide structures. The purpose of this investigation was to explore how an organic binder based on …

Pelletization Using Humic Substance-based Binder
ABSTRACT Humic substances exist widely in lignite coal as high molecular weight organic molecules. They can be used as binders in iron ore pelletization mostly in the form of salt, such as sodium humate and amine humate via extraction from lignite coal. It is worth determining if lignite can be used as a binder without extraction. As a composite binder of …
