The froth phase is one of the main components of froth flotation as it defines both the quality of the end product and overall efficiency. The performance of the froth depends on a number of sub-processes that interact in very complex ways, and it is a great research challenge to explicitly name the role of each of these sub-processes.

Furthermore, the stagnant volume in large cells can also affect mean cell residence time distribution and flotation performance (Lelinski et al., 2002). Consequently, the study of hydrodynamics of flotation cell scale-up is of significance for the optimization of industrial flotation performance.

The collection zone residence time distribution (RTD) of mechanical self-aerated flotation cells was characterized for liquid and solid per size class (−45 µm, +45–150 µm and +150 µm). It was found that a single large industrial cell with a volume of 130 to 250 m3, now used in plant operations, can be well represented by an LTST (large …

Complex and non-sulfide lead–zinc ores are difficult to concentrate, but the growing demand for lead and zinc metals necessitated their beneficiation. Froth flotation is practically the most effective method in their beneficiation when optimum flotation conditions are attained. The aim of the current study is to use process mineralogy as a …

While traditional flotation cells achieve good performance in the size range of 20-250μm, they can struggle when the size range is below 40μm or above 200μm. The chemistry design requirements for floating coarse particles have been known for a long time, but the physics of traditional flotation cells - primarily froth zone dynamics ...

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.

This class of flotation devices is sometimes referred to as "two-stage flotation cells." Eriez developed and patented its two-stage device, called the StackCell in 2008. Today, the company has more than 30 fullscale installations in coal flotation. A cut-away of the Stack- Cell is shown as Figure 2. The design features a tank within a tank.
