SELECTION OF MECHANICAL FLOTATION EQUIPMENT
Modern flotation cell design is based on a cylindrical tank (Figure 2), and these are ommonly known as c Tank Cells. The cylindrical tank design allows for a more even flow pattern than the earlier 'hog-trough' style cells and consequentlythese units have better air and solids dispersion throughout the tank. Each tank can have their

In these equations, c is the solids concentration, c 0 is the solids concentration in the feed, and is the mean retention time of the suspension. Comparing the above equations shows that theoretically a plug flow flotation cell is more efficient than a perfectly mixed system (for the same k and ); to put this another way, a smaller plug flow tank will …

Improving flotation energy efficiency by optimizing cell hydrodynamics
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.

What Are Column Flotation Cells?
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.
