The flotation process and related flotation cells are widely used for treating metallic and nonmetallic ores and in addition, it is receiving an ever widening application in other industries. A greater tonnage of ore is treated by flotation than by any other single process. Practically all the metallic minerals are being recovered by the flotation …

Modern flotation cell design is based on a cylindrical tank (Figure 2), and these are commonly known as Tank Cells. The cylindrical tank design allows for a more even flow pattern than the earlier 'hog-trough' style cells and consequently these units have better air and solids dispersion throughout the tank.

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 …

There are three different types of Imhoflot™ flotation cells; tangentially fed (G-cell), vertically fed (V-cell), and another type so-called H-cell, which is a combination …

The Reflux Flotation Cell (RFC), presented below in Fig. 1, is a novel flotation technology consisting of a vertical chamber located above a system of parallel inclined channels. The RFC uses a downcomer arrangement to promote particle-bubble collision and attachment [6], where compressed air is introduced to the feed slurry via a …

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 …

Parada, 2019). Flotation cells' froth transport characteristics can be consistently correlated with flotation performance, as they affect the time that particles reside in the froth phase and, consequently, the probability that they survive the froth phase; (Li et al., 2014). Flotation cells' considerable increase in effective volume and froth

The recovery of a cell or bank depends on the operational and design parameters. Some of the main factors affecting the efficiency of the flotation circuit are the pulp chemical conditions ... the flotation circuit configuration is not very se nsitive to stage recovery [9,19 ]. The overall output

Flotation cell diameters and the amounts of water in which air bubbles are intended to be formed; R = 0.92 m cell diameter is determined by taking into account 1 m 3, R = 1.30 m cell diameter 2 m 3 and R = 1.60 m cell diameter 3 m 3 water. Continuous water ingress was provided to the cells from the outside and the current was cut off after ...

Flotation machines, in general, may be categorized into four different classes: (i) mechanical or con- ventional cells; (ii) energy-intensive pneumatic cells; (iii) column …

Pneumatic flotation cells are typically classified as high-intensity flotation machines with rapid kinetics, resulting in short residence times, often half that of mechanical flotation cells and a ...

Sized column flotation circuit treating 0.150 x 0.045 mm (100 x 325 mesh) feed. This column flotation cell uses the SlamJet air sparger. The sparger is an air lance

In flotation process, the efficiency and selectivity depend on mineralogy, particle size distribution and liberation, reagents added, mixing, and particle coverage. However, the kinetics of particle recovery is highly dependent on cell hydrodynamic and circuit configuration and operational strategy. Controlling froth depth and gas flow rate, …

A froth flotation cell consists typically of a collection zone (or pulp zone) located below the feed particle point, and a cleaning zone, (or froth zone), above the particle feed point [26] (Figure 2). The collection zone is fed back-stream by the pulp pushed by the bubble swarm created by a gas sparger at the bottom of the flotation cell.

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 flotation, …

A dual flotation–conductivity laboratory flotation cell was implemented to study the effect of gas dispersion variables, including frother concentration, on the flotation performance. For a given flotation time, the cumulative copper recovery exhibited a fairly linear function of gas rate, and this relationship was modified by frother ...

For non-Newtonian flotation pulps, rheology is strongly dependent on the shear rate in a flotation cell [41, 42]. In several studies on pulp viscosity measurement (e.g., [19, 39, 43, 44]), apparent viscosity was obtained at 100 s −1 or 160 s −1 which are claimed to represent a typical shear rate in a mechanical flotation cell [19, 45].

This article summarises, from information supplied by the manufacturers mentioned, the latest trends in flotation equipment design.

Yianatos [ 11] in 2008 reported the bubble loading in an industrial copper flotation cell as 26.5 g/L and 59.0 g/L (about 0.006 mg/mm 2 and 0.010 mg/mm 2 ). In recent studies, the bubble loading in column flotation of quartz has been found to be in the range of 0.01 to 0.04 mg/mm 2 [ 16, 17 ]. A direct relationship between collector dosage …
