The Effect of Bubble Size on Fine Particle Flotation

Abstract Expressions for the probability of collision (Pc) and adhesion (Pa) have been derived for fine particle flotation by calculating the trajectory of particles as they flow past a bubble in streamline How Three different flow regimes have been considered in the present work i e Stokes potential and intermediate For the intermediate

On the Role of Bubble Size in Column Flotation

The results showed a significant bias between experimental and predicted data using the model of Gorain et al (1997) possibly reflecting the model's inability to explain the impact of bubble size bubble rise velocity and flow regime on E The model of Hernandez-Aguilar et al (2010) well described the experimental evidence
