Electrochemistry of Pyrite Flotation: Evaluation of Length of Hydrophobic Interactions between Mineral and Air Bubble from the Induction Time Measurement

摘要：

The work presented shows results of electrochemical study of pyrite hydrophobicity evaluated by air bubble induction time (IT) measurements. On the basis of measured ITs an average thickness of the thin liquid film prior to its rupture has been evaluated, which confirms long-range character of the interactions between air bubbles and hydrophobic surfaces. Obtained data are discussed in the frame of recent studies of structures of solid-liquid interface based on molecular dynamics simulations and results of surface force measurements.
