The REFLUX™ Flotation Cell (RFC™) combines several technologies to achieve superior flotation performance at a magnitude far beyond the capacity of existing flotation devices. This technology was developed by FLS in collaboration with Prof. Kevin Galvin and his team at the University of Newcastle, Australia who is also the inventor.
A new type of device, a dissolved-air flotation column, was developed for separation of oily wastewater. The unique design idea of the dissolved-air flotation column is the combined use of ...

Latest News Outotec is deploying its Concorde cell flotation technology for a "major nickel producer in Western Australia" with start-up of the new flotation cells set to commence in 2022. According to a company statement, the producer is one of the largest nickel-producing sites in the world.
Figure 1: Flotation 'triangle' showing the factors affecting performance. The Jameson Cell technology was first introduced in the late 1980s to overcome the design and operating inadequacies that were being experienced with column and conventional flotation cells. From the first commercial installation at Mt Isa in 1989,
The Air Flow Number should lie within a narrow range for optimum flotation results for any one cell. Harris gives values for most commercial cells while Table 4 has more detailed data for Denver and Wemco cells based on more recent measurements for sizes up to over 30m (1,000 cu. ft.).
New flotation-cell designs and process-control tools keep bubbling to the surface. By Russell A. Carter, Managing Editor. In the never-ending battle to gain tighter control over …
Mechanical flotation cells utilise an impellor to agitate the slurry and produce turbulent regions for bubble particle attachment, whereas in pneumatic flotation cells pulp and air are introduced together into the cell through a nozzle, also termed a downcomer, that promotes bubble-particle contact (Gupta and Yan, 2016).
In addition, a jet type flotation machine and a Jameson cell are also jet ing type flotation devices, and the bubble generation mechanism is similar to that of a bubble generator. Zhu et al. [ 51 ] found that seven obvious vortexes occur in a jet-type flotation machine, in which two vortexes in the inhalation section are advantageous for ...
flotation process, which hasn't changed fundamentally in 100+ years. the first of these is the Hydrofloat™, a high-efficiency, aerated, fluidized-bed flotation cell that is capable of recovering coarse, semi-liberated particles. Benchmarking the performance of the Hydrofloat against a conventional stirred tank cell in a number of
Mechanical flotation cells can be broken down into two broad categories based on how air is introduced to the cell. In a self aspirated flotation cell air is introduced to the slurry, the vacuum created by the rotorusing . In a forced air flotation cell air is generated external to the cell by a low pressure blower,, and pumped down the
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 …
Variables of hydrodynamics are equally important as those of surface chemistry in determining the efficiency of froth flotation processes. In a mechanical flotation cell, macro hydrodynamics is responsible for solids suspension and aggregates transport, and micro-turbulence plays an important role in the sub-processes of …

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.
