Froth flotation - Wikipedia

Flotation can be performed in rectangular or cylindrical mechanically agitated cells or tanks, flotation columns, Jameson Cells or deinking flotation machines. Classified by the method of air absorption manner, it is fair to state that two distinct groups of flotation equipment have arisen:pneumatic and mechanical machines.


are no Eps for flotation equipment and their performance must be determined by tes’ t work. Although the fines circuits treat a much smaller proportion of the raw coal feed compared to the gravity circuits, it can still play a vital role in controlling the overall product quality from the plant.

Jameson cell - Wikipedia

The Jameson Cell is a high-intensity froth flotation cell that was invented by Laureate Professor Graeme Jameson of the University of Newcastle (Australia) and developed in conjunction with Mount Isa Mines Limited ("MIM", a subsidiary of MIM Holdings Limited and now part of the Glencore group of companies).

Flotation Process - an overview | ScienceDirect Topics

Flotation processes are based on the different surface wettability properties of materials (Wang et al., ). In principle, flotation works very similarly to a sink and float process, where the density characteristics of the materials, with respect to that of the medium where they are placed are at the base of the separation.
