Optimizing Flotation Cells
Flotation Cells (Froth Flotation) were developed to separate and recover high value Sulphide ores from low grade ore bodies. The ore is crushed and milled at the concentrator in a process known as comminution, where the mineral is in suspension in slurry. The particle size for mineral being recovered is generally less than <0.1mm.
Flotation Cell
The purpose of the flotation cell is to attach hydrophobic particles to air bubbles, so that they can float to the surface, form a froth, and can be removed.

Adjusting Pulp and Air Levels to Troubleshoot Flotation Cell Froth Movement
The first corrective reaction is to raise the pulp level or add air to the cells to quickly increase the overflow. As a band aid solution this is correct, but as the ultimate correction it is not. The purpose of the air is to provide the medium that the collector attaches and to provide a surface for the mineral to be floated away on.

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.
