摘要：

矿物表面粗糙度的特征影响着液-固和气-固相互作用，从而影响矿物颗粒的疏水性以及气泡矿化过程。尽管已经有很多研究对矿物表面粗糙度与浮选过程的关系进行了探索，但仍然存在一些待解决的问题，如矿物表面粗糙度的准确表征方法以及粗糙度对不同疏水性矿物浮选过程的影响。针对上述问题，从矿物表面粗糙度的定义、测量方法和制备方法出发，深入分析了粗糙度对表面润湿性、浮选药剂吸附、气泡-矿物表面接触面积和粘附力、诱导时间以及浮选效果的影响，旨在探讨矿物表面粗糙度对浮选过程的影响，揭示不同粗糙度对液滴-矿物相互作用和气泡-矿物相互作用的影响机制，为提高矿物浮选效率提供理论支持。

Abstract:

The importance of mineral surface roughness in the flotation process has attracted significant attention, as it directly influences the interactions between minerals, collectors, and bubbles. Despite extensive research exploring the relationship between mineral surface roughness and flotation processes, several unresolved issues remain, such as accurate characterization methods for mineral surface roughness and the impact of roughness on flotation processes involving minerals with different hydrophobicity. Characteristics of mineral surface roughness affect liquid-solid and gas-solid interactions, thereby influencing mineral particle hydrophobicity and bubble mineralization processes. Starting from the definition, measurement methods, and preparation techniques of mineral surface roughness, this paper thoroughly analyzes the effects of roughness on surface wetting properties, flotation reagent adsorption, bubble-mineral surface contact area and adhesion force, induction time, and flotation performance. The aim is to explore the influence of mineral surface roughness on the flotation process, elucidate the mechanisms by which different roughness affects liquid-solid and bubble-mineral interactions, and provide theoretical support for improving mineral flotation efficiency.
