A Review of Flotation Physical Froth Flow Modifiers
Over the past few decades, the need to process more minerals while lowering capital costs has led to an increase in the size of flotation cells, e.g., 0.03 m3 to 1000 m3. However, this increase has created new challenges in the operation and design of industrial flotation cells, particularly in terms of froth removal, because the distance the …

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.
