Conventional and column flotation machines achieve the same objective of recovering fine hydrophobic particles but varying in their methods and efficiency of separation (Figure 1.1). Typically, a conventional machine consists of a large cell where the flotation feed enters the lower portion and is mixed axially by a rotating impeller.
Unfortunately, the conventional flotation cell achieves high recovery only in limited size ranges. For example, a sulfide ore might float very well at 90 to 120 microns, but not at 50 or 150 microns. The research to date has identified two main reasons for the upper limit on floatable particle sizes.

hydraulically entrained in the froth of conventional flotation machines. column flotation does have its own set of design challenges though. the first of these challenges is simply the size of the column. the cell must be tall in order to achieve the desired residence time and minimize internal mixing which can be detrimental to cell
Flotation system is based around a group of 6 float cells arranged in a circular tank, each individual cell fitted with impellers, air spargers and froth launders. Host of benefits in the design; better mixing in slurry applications, resulting in greater efficiency for reactions and a greater uniformity within the tank.
A bank of conventional cells was operated in parallel with the column. While overall recoveries were marginal for both the column and conventional cell, average concentrate grades were higher for the column. Flotation feed grade was 0.006 to 0.01 oz/st Au with 0.1 to 0.3 oz/st Au column concentrate and 0.05 to 0.20 oz/st Au conventional
The Jameson Cell is a high intensity froth flotation cell that was invented by Laureate Professor . In a conventional flotation column, the void fraction is similarly low, and so a much more compact column design than conventional column flotation cells . Summary

no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5 Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.

A flash flotation cell is designed differently to a conventional mechanical flotation cell in that it operates at higher pulp densities and with coarser feed compared to conventional flotation cells.
The tailings discharge, on conventional flotation machines, is on the opposite end of the cell from the feed, ensuring the slurry travel the entire length of the cell past multiple banks containing impeller diffusers, before being discharged as tailings.
of impeller speed. The mechanism design is critical to ensure effective air pulp mixing and dispersion within the cell. The low pressure DR flotation machine requires air. An air pipe surrounding the impeller shaft leads directly to the centre of the impeller. DR flotation machines 2 DR Flotation

The most important of these is the ability to achieve high separation efficiencies using only a single stage of processing. Unfortunately, industrial flotation columns often suffer from poor recovery, low throughput and high maintenance requirements as compared to mechanically agitated conventional cells.
The increased use of flotation columns is due to their superior separation efficiency compared to conventional flotation. This increased efficiency can be attributed to The countercurrent movement of slurry and air bubbles increases the probability of bubble / particle attachment. This is accomplished by larger aerated volume of the cell, longer concentration gradient between froth and sinks
provides a surge capacity, dampening the incoming flow, allowing the flotation process to properly function. It also provides a buffer for free oil removal and skimming, lowering the oil content of the process before entering the first active cell. Following the initial quiescent cell is four (4) active cells.
