    To efficiently, flotation cells depend on continuous froth formation. If the froth layer is too thin, it cannot transport the sufficient amount of dispersed or suspended particles to the surface. On the other hand, froth that is too thick indicates that the reaction time of the chemicals is too long.

    In Mineral Processing Design and Operations (Second Edition), 2016. 18.5.1 Batch Flotation. The concentrate obtained from a batch flotation cell changes in character with time as the particles floating change in size, grade and quantity. In the same way, the concentrate from the last few cells in a continuous bank is different from that removed from the earlier cells.

  • Flotation cell OilfieldWiki

    Flotation involves the introduction of gas or air into the water to create a foam or froth which will scrub the solids from the liquid and carry them out with the foam. The primary difference in flotation cells is the two ways of introducing the gas.

    In the mechanical flotation cells the feed can be introduced directly to the impeller zone from the side as in a Denver-style Sub A sub-aeration machine.. A centrally located paddle-wheel type impeller generates a rotating pulp vortex which extends between two stationary elements: the sand-pipe located at the top of the cell, and the draft tube located at the bottom of the cell.

In some cases, new plants have selected tank cells as the machine of cho. Typical tank cells use high efficiency impellers for mixing, which


    Almost all successful models of the flotation process have been based on the premise that flotation is a kinetic process. In this way a model can be formulated in terms of a rate of flotation which can be quantified in terms of some of the many chemical and physical factors that define the environment inside a flotation cell.

    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. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.

    Coal flotation is commonly carried out with a combination of an oily collector (e.g. fuel oil) and a frother (e.g. MIBC). All coal flotation systems require the addition of a frother to generate small bubbles and to create a stable froth (Table 12.2).Typical addition rates for frothers are in the order of 0.05–0.3 kg of reagent per tonne of coal feed.
