    Flotation Machine An Overview Sciencedirect Topics

    Modern flotation machines are highintensity equipment designed to create very small bubbles and higher flotation rates. Smaller bubbles are generated by intensive mixing of pulps with air so that fast collisions between particles and bubbles take place. Microcel machines work with forced air, whereas the Jameson cell works with induced air.

    Whatever flotation machine design is chosen, it must perform a series of complicated functions. Some of the more obvious are Good mixing of pulp. To be effective, a flotation machine should maintain all particles uniformly in suspension within the pulp, including those of relatively high density anchor size. Good mixing of pulp is required for maximizing bubbleparticle frequency.

    Abstract Froth flotation is the dominating mineral beneficiation technique and has achieved great commercial success. This process has also found many applications in other industries where physical separation of materials is needed. However, its high process efficiency is often limited to a narrow particle size range of approximately 10100 m.
