摘要:Oily collector emulsions have emerged as an effective approach to enhance flotation performance and reduce reagent consumption in fine and low-rank mineral processing. This review systematically summarizes recent advances in the preparation, characterization, and flotation mechanisms of emulsified collectors. Various emulsification techniques including mechanical shear, ultrasonic, jet, and combined methods are compared in terms of droplet size control, energy efficiency, and scalability. The characterization of emulsion properties is discussed from multiple perspectives, including droplet size distribution, interfacial tension, stability evaluation, and the key factors affecting stability during flotation. The effects of emulsion properties on flotation behavior are further analyzed. Oil droplet size governs collector dispersion and particle–bubble interactions, while different emulsion types exhibit distinct mechanisms: oil-in-water (O/W) systems improve fine particle attachment, water-in-oil (W/O) systems promote selective agglomeration, and Pickering emulsions stabilized by solid particles provide superior stability and environmental compatibility. Finally, the review outlines future research directions, emphasizing the need for multi-field coupled emulsification devices guided by CFD simulation, real-time monitoring of emulsion dynamics, and the design of biodegradable or particle-based stabilizers. These insights provide theoretical and technological foundations for developing efficient, stable, and green emulsified collectors in mineral flotation.
