flotation separation froth

  • Flotation Froth an overview ScienceDirect Topics

    Froth flotation is a physicochemical process that separates particles based on differences in surface wettability Flotation takes place by passing finely dispersed air bubbles through an aqueous suspension of particles (Fig 17) A chemical reagent, called a frother, is

  • Separation of plastics by froth flotation The role of

    Flotation separation of plastics can be enhanced by differences in hydrophobicity In addition, flotation separation improves if the most hydrophobic plastic, that floats, has a lamellar shape and lower density and if the most hydrophilic plastic, that sinks, has a regular shape and higher density The results obtained show that froth flotation
