Studies of Bitumen Aeration
… and bitumen. It has been found that the film thinning kinetics increases in the order of asphaltene, bitumen, and maltene, and that the kinetics increases sharply with increasing temperature. In addition to obtaining kinetic information, the temporal and spatial profiles of the wetting films …

The synergistic interaction between dithiophosphate and frothers at the air-water and mineral-water interface
… the bubble and the particle, improving film thinning kinetics and synergistically enhanced mineral recovery. When DTP did not adsorb onto the mineral surface, the collector co-adsorbed with the frother at the air-water interface and transferred with the frother onto the mineral surface during …

Hydrophobic Forces in Wetting Films
… In the present work, we have measured the kinetics of film thinning between air bubble and flat surfaces of gold and silica. The former was hydrophobized by ex-site potassium amyl xanthate, while the latter by in-site Octadecyltrimetylammonium chlroride. The kinetics curves obtained with …

Effect of Non-Ionic Surfactants and Nano-Particles on the Stability of Foams
… Waals force, which may explain the faster film thinning kinetics. With a given non-ionic surfactant, the hydrophobic force decreased with increasing surfactant concentration, which explained the slower kinetics observed at higher concentrations and hence the increased foam stability. At …
