- Abstract
Traditional oil-based collectors have poor performance in recovering difficult-to-float coal slurry such as fine coal, low-rank coal, and oxidized coal. The development of new and efficient flotation reagents and processes is currently a challenging task. Nanotechnology, as a cutting-edge technology, has shown broad application prospects in the field of mineral processing and has received extensive attention and exploration. The progress of research on the use of nanoparticles as mineral flotation collectors is discussed. It highlights the design, synthesis, and application status of novel hydrophobic nanoparticles in flotation. These include anionic and cationic polystyrene nanoparticles, as well as functionalized nanoparticles with better selective adsorption effects. These nanoparticles exhibit excellent flotation performance and can effectively recover difficult-to-float coal and fine mineral resources. In addition, the microscopic interaction mechanism of nanoparticle-mineral interfaces is discussed. The size and surface properties of nanoparticles play an important role in their interaction with minerals. Anionic and cationic polystyrene nanoparticles are hydrophobic and can interact with hydrophobic minerals in coal slurry, enhancing their flotation performance. On the other hand, functionalized nanoparticles can achieve better selective adsorption effects on specific minerals through surface modification. Understanding these micro-interaction mechanisms helps optimize the design and synthesis of nanoparticles and improve their application effectiveness in mineral flotation. Finally, some suggestions were proposed for the research direction of novel nanoparticle collectors. The rapid development of nanotechnology will drive continuous progress and change in the field of mineral flotation, bringing new vitality and opportunities to the mining industry. nanotechnology will play a more important role in mineral flotation.
