The FDB cell was then raised, and the dropback, concentrate sample weights were determined. The froth recovery ( Rf) was measured as, (2) R f = C ( C + D) × 100 where C is the concentrate solid flowrate of attached and entrained particles and D is the dropback solid flowrate of attached and entrained particles.
The Jameson Cell was a joint development between Mount Isa Mines and Prof. G.J. Jameson of the University of Newcastle, Australia ( Jameson, 1988 ).

Froth flotation is the most versatile process in mineral beneficiation, extensively used to concentrate a wide range of minerals. This process comprises mixtures of more or less liberated minerals, water, air, and various chemical reagents, involving a series of intermingled multiphase physical and chemical phenomena in the aqueous environment. …
3.4. Effect of cell hydrodynamics on flotation performance. Overall recovery (R O) in a flotation cell is a function of recovery in the collection (R C) and froth (R f) phase, Eq. (4), ( Dobby, 1984 ): (4) R o = R f R c R f R c + 1 - R C. The drivers of recovery are very different in these two phases.
The first corrective reaction is to raise the pulp level or add air to the cells to quickly increase the overflow. As a band aid solution this is correct, but as the ultimate correction it is not. The purpose of the air is to provide the medium that the collector attaches and to provide a surface for the mineral to be floated away on.
The physical activities in a flotation cell involve the movement of solid particles driven by the flow of air and liquid. As illustrated in Fig. 1, Fig. 5, considering the different roles of pulp and froth in determining the cell dynamics, the flotation cell is divided into two sections: froth volume and pulp volume.The froth volume and pulp …

The Deister Flotaire Column Flotation Cell was originally designed and developed to process coarse and hard-to-float phosphate minerals, and was first commercialized in 1977. Shortly after its introduction, 15 full-size 2.4 m (8.0 ft.) dia. and numerous smaller diameter laboratory and pilot units were installed in the phosphate industry.

In general, froth flotation processes may be used for particles of 5–250 μm. The tendency of various materials to respond to froth flotation methods is discussed by Doughty. 19 Hanumanth and Williams 20, 21 have published details of the design and operation of laboratory flotation cells and the effect of froth height on the flotation of ...

Froth Flotation Handbook. What is Flotation. Flotation, as the term is applied to ore concentration, means the separation of one of the constituents of an ore from the remainder by causing it to float at or above the surface of a pulp consisting of the finely pulverized ore and water. Minerals that float. Minerals that float have a metallic ...

Column flotation cells utilise froth washing. Froth washing involves introducing clean wash water within the froth or externally on top of the froth. The added clean wash water creates a net downward flow of water in the froth, which flushes out gangue particles and reduces the fraction of gangue minerals [27,28,29,30,32,33]. Thus, …
Thus, it is suggested that the cleaner flotation cell operates at high froth depth and low gas rate to improve the froth retention time and upgrading in the froth zone (Cooper et al., 2004;Schwarz ...
