On modeling of public bubble-particle attachment probability in flotation

摘要

We have developed the theoretical basis forexperimental determination of bubble-particle attachmentprobability in single-bubble flotation experiments. We use theseexperimentally determined data to simulate the dependence ofinduction time on particlesize. Using these simulated results, weverify the bubble-particle attachment probability predictiondeveloped on the basis of sliding time and induction time. Wehave calculated the induction time of fine quartz particles ofdifferent diameters less than 80 ?m and different hydrophobicity,collected by single bubbles with diameters of 0.75 mm, 1.2 mm,and 2.0mm. The simulation reported in this present paper shoesthat the calculated induction times increase with decreasingparticle size, except for particles of strong hydrophobicitycollected by the small bubbles with a diameter of 0.7 mm.
