摘要 介绍了一种潜在的从稀水悬浮液中快速固/液分离细颗粒的方法（翻滚法）。该过程涉及通过异质凝结现象分离水悬浮液中的一种或两种细颗粒，并通过用宏观收集器（例如玻璃珠）翻滚悬浮液来进行，这导致颗粒在收集器中沉降。特别地，发现二氧化硅(SiO 2 ：0.12μm)颗粒可以通过赤铁矿(α-Fe 2 O 3 ：0.10μm)颗粒的桥联效应被玻璃珠(80μm)有效地收集。根据 DLVO 理论和玻璃珠收集器的有效运动对结果进行了解释。还提出了二氧化硅和赤铁矿颗粒之间的色谱分离。
Abstract A potential rapid solid/liquid separation process of fine particles from dilute aqueous suspensions is introduced (tumbling method). This process involves the separation of one or two types of fine particles in aqueous suspension by heterocoagulation phenomena and is conducted by tumbling suspensions with a macroscopic collector such as glass beads which leads to the settling of particles with the collector. Particularly, it was found that silica (Si02: 0.12 μm) particles could effectively be collected by glass beads (80 μ.m) through a bridging effect of hematite (α-Fe203 : 0.10 μm ) particles. The results were explained in terms of the DLVO theory and the efficient movement of the glass beads collector A chromatographic separation between silica and hematite particles is also proposed.
