摘要

The flotation of fine copper minerals has traditionally encountered challenges such as poor recovery, limited selectivity, and high reagent consumption due to the increased surface area of smaller particles. This paper explores the use of polystyrene nanoparticles as collectors in froth flotation, highlighting their properties such as high surface free energy, reactivity, large surface area, and adsorption capacity, which can improve the extraction of micro-fine copper minerals. Key factors such as hydrophobicity, selectivity, and interactions between polystyrene nanoparticles, mineral particles, and bubbles are emphasized. The synthesis and functionalization of these nano-collectors to achieve targeted properties is also discussed. An evaluation of prior experimental research on the influence of polystyrene nanoparticles on copper recovery is presented, focusing on variables such as particle size, dosage, pH, and surface modification. The review also identifies gaps in the literature and suggests approaches for enhancing copper recovery, concluding that polystyrene nano-collectors have significant potential as flotation collectors.
