Optimizing Flotation Cells. H ow a flotation cell works . Flotation Cells (Froth Flotation) were developed to separate and recover high value Sulphide ores from low grade ore bodies. The ore is crushed and milled at the concentrator in a process known as comminution, where the mineral is in suspension in slurry.
High energy consumption; Spare part wear life; Self-aspirated or poorly performing forced-air flotation cells can present a number of challenges, such as the process stability, the sanding and "wave effect".

The most common examples of pneumatic cells are the column cell and the Jameson cell.As shown in Fig. 5.36, a flotation column is typically a tall vertical cylinder.It is fed with coal pulp at the top third of column. It has no mobile parts or agitators. Air bubbles are injected either through external or internal spargers at the bottom.
The influence of flotation variables (Fig. 1) in varying degrees, and their interactions – on the one side, and distinct tendency of plant operators for achieving the process stability and products quality – on the other side, are conflicted in the domain of process control.Therefore, the control of such a process is highly specific and very …
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 ...

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.
The Concorde Cell is an enhanced pneumatic high-intensity forced-air flotation type of technology. Unlike agitated flotation, pneumatic flotation involves mixing the air and the pulp in a continuous stream, thereby separating contact and froth treatment …
Additionally, the use of high frother concentration can result in persistent and too stable froth formation, leading to overflow in the flotation cells, pumping problems and handling difficulties in the flotation concentrator (Bournival et al., 2017a, Wei et al., 2014). As a consequence of this significant influence of frothers on the overall ...
particle contacting in a high-shear environment. Through froth washing, our Column Flotation Cells offer advanced performance and consistently produce a high-grade product. As an integral part of a flotation circuit, column flotation is highly effective in producing high-quality product, offering superior recovery of fine materials.
Column flotation cells, like mechanical cells, are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Instead, mixing is achieved by the turbulence provided by the rising bubbles. Columns are mostly used to produce final grade concentrates because they are capable of high selectivity.
In the mineral processing field, flotation techniques have witnessed significant trends and best practices that are shaping the industry. One prominent trend is the increasing reliance on digitalization and data analytics. Mining companies are investing in advanced sensors, data integration, and machine learning to gain deeper insights into …
Feed and air are contacted in a high shear rate environment as it enters the cell via a central sparging system to expedite froth flotation kinetics. The float product emerges through an annulus surrounding the sparger system, while the tailings discharge via the zone below the inclined channels.
The Jameson Cell technology is an established robust and efficient high intensity flotation technology which has been continuously developed and improved over two decades. Its high capacity, small footprint and low maintenance requirements have made it more or less a standard flotation technology in the Australian coal industry.
Mechanical cells usually have a higher throughput rate, but end up producing lower quality material, while flotation columns work the other way around, with a lower throughput rate but higher quality material. The Jameson cell just combines the slurry with air in a downcomer: then, a high shear creates the turbulent conditions …
