摘要: Pure mineral flotation experiments, zeta potential testing, and infrared spectroscopy were employed to investigate the interfacial reactions of oleic acid (collector), sodium dodecyl benzene sulfonate (SDBS, synergist), rhodochrosite in an anionic system. The pure test shows that has a strong ability collect products on rhodochrosite. Under neutral moderately alkaline conditions, low temperature (e.g., 10°C) adversely affects performance acid; addition SDBS significantly improves dispersion solubility acid, enhancing its collecting recovery. interacts with SDBS, resulting more negative co-adsorption collector synergist at surface. Infrared demonstrated when are used as mixed collector, oleates along –COO– –COOH functional groups formed surface, indicating chemical adsorption results demonstrate co-adsorb chemically surface rhodochrosite, thereby improving collector.
