ABSTRACT
An approach, reffered to here as the Scheludko-Malysa approximation has been used for the calculation of thickness of the rupturing film from the experimental values of air bubble – platinum, and air bubble – sulphide minerals, induction time (IT). The influence of applied potentials, pH, and flotation collectors on wettability is discussed. The results indicated a broad variation of IT. Calculated thickness of the rupturing film reaches some microns. It confirms a long-range character of the interactions between air bubbles and hydrophobic surfaces.
