Fluid Flow and Kinetic Modelling in Flotation Related Processes

Figure 3 (a) shows a scheme of the classical flotation column design, considering counter-current contact between the pulp feed and a bubble swarm, generated by the gas sparger near the bottom of the column (Finch and Dobby, 1990). The feed pulp descends by gravity allowing that hydrophobic particles collide and adhere to the bubbles.The Jameson Cell was a joint development between Mount Isa Mines and Prof. G.J. Jameson of the University of Newcastle, Australia (Jameson, 1988). Since its invention in 1986 there have been 225 Jameson Cells installed in a variety of applications.

Minerals Free Full-Text A Review on Froth Washing in Flotation

In column flotation cells and Jameson cells, wash water is added to the entire froth surface. The literature also indicates that the wash-water rate, wash-water quality, type of wash-water delivery/ distribution mechanism and the area covered by wash water are critical parameters that dictate the efficacy of the washing system.
