flotation cell bubbles

that the bubbles can attach to the surface. If the bubbles and surfaces never come in contact, then no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell

    Effect of Turbulence in Fine Bubbles Flotation

    Dec 06, 2017 Fine bubble flotation was conducted in a modified 500-g MS flotation cell. A 6-cm-diam by 2-mm-thick disk was used to replace the flotation impeller. Sebba (1985) showed that at high rotation speeds the spinning disk sheared air in the pulp and formed fine-sized bubbles

    in a mechanical Sotation cell is dispersion of gas into Rne bubbles. The bubble generation mechanism in a mechanical cell is a two-stage process. Firstly, air cavities are formedat the trailing edge of the impeller blades, which is the low pressure region. Thereafter, bubbles form by shedding of vortices from the tail of the cavity, as shown in Figure 3
