中文摘要

絮凝浮选是回收微细粒矿物最有效的方法，其本质在于絮凝体的浮选和回收。絮凝体的基本物理特性主要由其表观粒径和结构（密度和形态）决定。目前，关于絮凝体特性对颗粒沉降和水处理的影响已进行了大量研究。然而，有关絮凝体特性对浮选的影响并未得到广泛研究。本研究基于絮凝体形成和絮凝浮选，从絮凝体粒径和结构的角度概述了絮凝体的基本物理特性，并总结了絮凝体粒径和结构之间的交互作用。此外，本文深入探讨了絮凝体粒径和结构对絮凝体可浮性的影响，进一步揭示了絮凝体特性对气泡碰撞和粘附的影响，阐明了絮凝体与气泡之间相互作用的机制。总结发现，絮凝体粒径并不是影响絮凝浮选的唯一因素。在适宜的表观粒径下，结构密实的絮凝体在浮选时，与气泡碰撞、粘附的效率更高，浮选效果更好。本文旨在为絮凝浮选提供参考，以期未来能开发出更高效、精细的絮凝浮选工艺。

Abstract

Abstract

Flocculation flotation is the most efficient method for recovering fine-grained minerals, and its essence lies in flotation and recovery of flocs. Fundamental physical characteristics of flocs are mainly determined by their apparent particle size and structure (density and morphology). Substantial researches have been conducted regarding the effect of floc characteristics on particle settling and water treatment. However, the influence of floc characteristics on flotation has not been widely studied. Based on the floc formation and flocculation flotation, this study reviews the fundamental physical characteristics of flocs from the perspectives of floc particle size and structure, summarizing the interaction between floc particle size and structure. Moreover, it thoroughly discusses the effect of floc particle size and structure on floc floatability, further revealing the influence of floc characteristics on bubble collision and adhesion and elucidating the mechanisms of interaction between flocs and bubbles. Thus, it is observed that floc particle size is not the only factor influencing flocculation flotation. Within the appropriate apparent particle size range, flocs with a compact structure exhibit higher efficiency in bubble collision and adhesion during flotation, thereby resulting in enhanced flotation performance. This study aims to provide a reference for flocculation flotation, targeting the development of more efficient and refined flocculation flotation processes in the future.
