    Figure 4. If the contact angle is very small, then the bubble does not attach to the surface, while a very large contact angle results in very strong bubble attachment. A contact angle near 90 is sufficient for effective froth flotation in most cases. Figure 4: Contact angle between and air bubble and a solid surface immersed in liquid.

    Air Bubble Size Measurement In A Laboratory Flotation

    Air bubble size distribution in a laboratory flotation cell was investigated by using of image analysis technology in this paper. Results showed that it was feasible to determine the air bubble size according to image analysis software. For a porous media-aerated flotation cell, bubble size was dependent on poles size of porous media.

    Oct 19, 2007 1. Gas dispersion sensors. Gas dispersion is the collective term for superficial gas (air) velocity (or gas rate, volumetric air flow rate per unit cross-sectional area of cell, J g), gas-holdup (volumetric fraction of gas in a gas–slurry mix, ε g), and bubble size distribution (D b).The sensors and devices we have used to measure these variables in flotation machines have been described in ...

  • Role Of Sparger Configuration In Determining Flotation

    Role Of Sparger Configuration In Determining Flotation

    Bubble size is crucial for determining flotation efficiency. Fine bubbles can be cost-effectively generated using a multi-orifice sparger with oscillatory air supply. Sparger configuration is defined by the orifice size, the plate thickness and the chamber volume. To date, the effect of sparger configuration on bubble size with oscillatory air supply is not clear yet.

    Reagent Dosages Control Based On Bubble Size

    The reagent dosages can directly affect the concentrate grade and recovery in the mineral flotation process. For many years, the dosage has mainly been controlled by human observation of froth image features, especially the bubble size. However, the reagent dosage control based on human experience can easily cause fluctuation of the performance index, which may result in wasted ore resources ...
