The Effect of Polystyrene on the Carrier Flotation of Fine

Carrier flotation is a common technique used to improve flotation recovery of ultrafine ores. In this study we used coarse polystyrene as the carrier material to enhance flotation recovery of fine smithsonite (ZnCO3) particles. Sodium oleate was used as the collector and played a role in the adhesion of fine smithsonite to polystyrene due to its amphipathic properties. The carrier feature of

The Limits of Fine and Coarse Particle FlotationDe F

Turbulence plays a role as does bubble‐particle aggregate velocity and bubble size. The stability of the bubble‐particle aggregate controls the maximum floatable particle size of coarse particles. For fine particles the flotation limit is dictated by the energy required to rupture the intervening liquid film between the particle and bubble.
