doi:10. 11799/ ce202503024

Abstract

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.
