3.4. Effect of cell hydrodynamics on flotation performance. Overall recovery (R O) in a flotation cell is a function of recovery in the collection (R C) and froth (R f) phase, Eq. (4), ( Dobby, 1984 ): (4) R o = R f R c R f R c + 1 - R C. The drivers of recovery are very different in these two phases.

Flotation equipment is a kind of beneficiation equipment which takes bubbles as the carrier and uses the difference in mineral surface wettability to separate minerals. In the late nineteenth century, flotation as a beneficiation method was explicitly proposed, and various types of flotation equipment were developed, including flotation …

mechanism historically utilized in mechanical float cells. Instead of operating with a large tank volume, the StackCell™ forces the bubbles and particles to contact within a small aeration chamber which is me-chanically isolated from the remainder of the tank.

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.

The Jameson Cell is a high intensity flotation cell in which pulp and air are brought together in a co-current descending flow in a vertical tube called the downcomer. The pulp is introduced into the downcomer through a slurry lens orifice to produce a high velocity jet that generates violent mixing and fine bubble size.

The other type of flotation cells is a column cell. Column cells are tall round tanks that use compressed air to create air bubbles via spargers or cavitation tubes. These cells are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Mixing is achieved by the turbulence provided by the rising bubbles.
