Nanobubble Enhances Rutile Flotation Separation in Styrene Phosphoric Acid System

Due to the weak hydrophobicity of styrene phosphoric acid (SPA), amount used as a collector for rutile flotation is too large, resulting in high beneficiation costs. In this study, SPA was modified by nanobubbles enhance its hydrophobicity. paper, modification and adsorption mechanism on surface before after were studied means nanoparticle tracking analysis, micro-bubble test, contact angle zeta potential etc. The results show that can significantly increase concentration bulk nanobubbles, recovery from 55% 69%, reduce dosage 101 mg/L 70 mg/L. Nanobubbles interact with form water drainage, reducing increasing solid–liquid interface surface. A model interaction between SPA, established, which helpful understand process nanobubble flotation.
