A key concept in the estimation of the probability of particle–bubble attachment is the induction time, t ind, which was first articulated by Sven-Nilsson (1934). Fundamentally the induction period accounts for thinning and drainage of the film of liquid interposed between the particle and the bubble, until rupture of the film occurs.

Attachment of particles and droplets to bubbles—the latter being of various fine sizes and created by different techniques (as described in detail)—forms the basis of flotation, a process which indeed was originated from mineral processing. Nevertheless, chemistry often plays a significant role in this area, in order for separation to be effective, …

Bubbles are one of the primary sources of transferring substances from water to air. When bubbles burst, small droplets containing microparticles and microorganisms previously suspended in water disperse. Hence, visualizing small objects in bubble films can provide a new methodology for investigatin …

The particles to be floated must be hydrophobic in order to selectively connect to air bubbles. The formation of a mineral-air interface and the destruction of an equivalent area of mineral-water and air-water interfaces cause a change in free energy during particle-bubble contact (Fuerstenau and Somasundaran, 2003).In this context, it …
