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 carboxymethyl cellulose structure improves the compressive strength of wet and dry pellets. Thus, the interaction between the binder Peridur® and the mineral surface and the content of goethite in two Brazilian pellet feed were investigated. This work has found that the same organic binder performs differently depending on the type of iron ore processed.

有机结合剂在绿色铁矿球团中的结合机制

摘要 在铁矿石球团工艺中，有机粘合剂已被用作膨润土的替代品，主要是因为它燃烧时不会在球团中留下残留物。有两种主要类型的有机粘合剂，一类是基于纤维素的，另一类是基于聚丙烯酰胺结构的。本研究的目的是探索基于羧甲基纤维素结构的有机粘合剂如何提高湿颗粒和干颗粒的抗压强度。因此，研究了粘合剂 Peridur® 与矿物表面之间的相互作用以及两种巴西颗粒饲料中针铁矿的含量。这项工作发现，相同的有机粘合剂根据加工的铁矿石类型而表现不同。
