In the conventional flotation cell, the detachment of particles from the bubbles due to turbulence is the main reason for the decline in the coarse particle recovery (De et al., 2007, Fuerstenau et al., 2007).However, turbulence is imperative in the flotation cell to bring about bubble particle collision, keep particles in suspension, and disperse air flow into fine bubbles.

Flotation cells have a wide range of applications in the field of particle separation as a traditional flotation unit. Due to the declining ore grades and the increasing market demand for mineral resources, recovering particles in a wider range of sizes efficiently is a challenge that plants must face, but which is not an advantage of traditional units.

In arriving at the larger cell sizes now available, which cover the range from 100 to 500 cu ft per cell, two different paths were taken by the manufacturers. The first larger cell, and the simplest to design, was the multi-spindle type, this is actually a compromise that lacks the major cost savings obtainable with the single mechanism in a ...

In principle, the cell functions as a shallow flotation cell. As the air and pulp are hydrau-lically lifted to the top of the pulp recircula-tion well, the mineral laden air bubble has only to travel a short distance on its own to the froth overflow level.
