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.

3 Reasons to Add Flotation to a Boat or Dock

Flotation acts as a life jacket for your boat. If the vessel is punctured and develops a hole or leak, it will still take on water, but the flotation will significantly slow the rate at which the boat sinks. In most cases, flotation provides enough time to radio for help and wait for a rescue, or to make it to shor…See more on empiresolutions

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.

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.
