Flotation Machine - an overview ScienceDirect Topics

Machines with large specific surface areas are generally preferred for coal flotation, due to the fast flotation kinetics of coal and the large froth solids loadings. Flotation machines with individual cell volumes of up to 28 m 3 are commonly used due to advantages in terms of capital, operating and maintenance costs.

Important Considerations in the Design of Mechanical ...

Mechanical flotation machine design is typically based on hydrodynamic analysis, with scale-up calculated by geometric proportionality. End users often specify and purchase machines on the basis of retention time, characterised by the $/m3' approach; they may also consider the manufacturer's installed base. In some applications, end users also consider specific energy and the impact of energy ...

The flotation rate constant is the value characterizing the kinetics of cyclic flotation. In the statistical theory of flotation its value is the function of probabilities of collision, adhesion and detachment of particle from the air bubble. The particle - air bubble collision plays a key role since there must be a prior collision before the particle - air bubble adhesion happens.
