In the conventional flotation cell, the detachment of particles from the bubbles due to turbulence is the main reason for the decline in the coarse particle recovery (De et al., 2007, Fuerstenau et al., 2007).However, turbulence is imperative in the flotation cell to bring about bubble particle collision, keep particles in suspension, and disperse …
Over the past few decades, the need to process more minerals while lowering capital costs has led to an increase in the size of flotation cells, e.g., 0.03 m3 to 1000 m3. However, this increase has created new challenges in the operation and design of industrial flotation cells, particularly in terms of froth removal, because the distance the …
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.
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.

Results show that our flotation machines operate on exceptional grade recovery curves, with respect to coarse and fine particle recovery. The remarkable performance of our machines is related to flotation-favourable hydrodynamics, which produce higher active cell volumes, provide longer residence times, and complement froth removal.
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.
The flotation chemistry is the same for both flash flotation and standard flotation, but the hydrodynamics and froth phase are quite different (Jameson, 1984, Yoon, 2000, Tsatouhas et al., 2006, Arellano-Piña et al., 2017). Although, in a flash cell, it is commonly accepted that coarse particles float, it should be considered that, by removing ...
