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.
Optimal mineral recovery in a flotation circuit depends on the capacity to adapt to metallurgical variability in the ore being processed. It is possible that some banks of flotation cells might not be recovering ore at their maximum levels due to air flow, feed, mechanical, hydraulic, reagent imbalances. Recognizing the need for a solution that ...

The effect of particle size on the flotation of coarse particles is analyzed. It is concluded that turbulence and the presence of the froth layer are detrimental to the recovery of coarse particles during conventional flotation. A counter-current column cell is proposed to avoid these two factors. In this column, a net upwards flow of water is …
The flotation process is a complex interaction between the physicochemical characte- ristics of the species involved and the hydrodynamic and operating conditions in flotation cells. Efficient cell design requires knowledge about the power to be provided and the time to be spent in the cell by each one of the phases.

Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered …
Following in-house research and successful pilot trials at Blackwater using Denver flotation cells, the first, large, froth flotation circuits were installed at the Blackwater mine in 1967. The Blackwater circuit used 75 m 3 (100 ft 3) Denver cells to process 0.5 mm × 0 raw fines. While this installation was successful, there was a …
