A collision between bubbles usually occurs based on their relative velocity, which may be caused by turbulent fluctuations of the slurry in the flotation cell. The slurry in the flotation cell moves irregularly, and the velocity and pressure at any point exhibits a high-frequency pulsation over time, resulting in a non-uniform velocity gradient ...
Jameson Cell has accurate scale-up reliability and is the real-word specification in any and all duties within a flotation circuit: rougher and scavenger duty; cleaner and cleaner scavenger duty. In fact, a single Jameson Cell has successfully replaced a traditional circuit of cells; and unlike other competing cells, it has no moving parts.

Semantic Scholar extracted view of "A novel scale-up approach for mechanical flotation cells" by J. Yianatos et al.
The operational proof-of-concept for the flotation cell class of 500 m3 and larger is discussed in this paper. Two different sites are used as case studies and metallurgical and hydrodynamic performance is evaluated as the means of comparison. Frother selection criteria are also discussed and a redesign on standard practices for scaling up to full …
The development of larger size flotation machines, which started in the 1950's and 1960's, is still proceeding. The largest mechanical flotation machines available today have unit volumes in the range of 38.2 to 43.9 m³ (1,350 to 1,550 cft). Designs for mechanical flotation .cells of unit volumes as large as 70.8 m³ (2500 cft) are available.
The flotation process for removing suspended materials from produced waters is widely used in the petroleum industry to improve the water quality.Flotation involves the introduction of gas or air into the water to create a or froth which will scrub the solids from the liquid and carry them out with the .
