高分子絮凝一直被认为是微细粒溺磁性矿物选择性聚团的有效方法之一。本研究在高分子絮凝过程中引入有少量磁种参与的极弱磁场磁（种）聚团机制,即极弱磁场复合高分子聚团,明显强化了高分子絮凝作用,在保持良好选择性的同时增强了聚团能力。通过较为深入的显微照相与表面物理化学研究,本文还将介绍这种复合聚团的粒间作用方式模型和能量模型,并揭示复合聚团机理。 Polymer flocculation has long been considered as one of the effective methods for the selective agglomeration of fine-grained ores. In this study, a very weak magnetic field (species) clustering mechanism involving a small amount of magnetic species was introduced into the polymer flocculation process. That is, the weak magnetic field composite macromolecule agglomeration significantly enhanced the flocculation of macromolecules. While maintaining good selectivity At the same time enhance the capacity of agglomeration. Through more in-depth photomicrography and surface physico-chemical studies, this article will also introduce the intergranular interaction mode and energy model of this complex, and reveal the complex polymerization mechanism.
