A simple empirical dimensionless model to calculate the mineral gangue recovered per size class (R G,i) by entrainment, in terms of the water recovery (R W), in an industrial flotation cell is presented.For modeling purposes, a dimensionless entrainment factor EF i, corresponding to the ratio (R G,i /R W), was defined for each particle size …
For this purpose, a froth image database was created using a special laboratory cell, designed to emulate the conditions seen in an industrial flotation cell. The database contains 2250 images, distributed in 45 categories; each category has a specific combination of testing conditions, and the main visual characteristics are observed.

Gas hold-up is measured by taking a sample of aerated slurry within the pulp phase of a flotation cell (Power et al., 2000).The gas hold-up probe is a vertical cylinder with pneumatic valves at the top and bottom of the cylinder (Fig. 3).The probe is lowered into the pulp phase of the cell and the valves are opened to allow pulp and bubbles to …
Pneumatic flotation, as developed by Dr. Rainer Imhof, has been successfully deployed in the minerals and environmental industry for over fifteen years. A recent innovation – the use of centrifugal forces in the separating vessel for rapid froth from tailings separation and removal – has added a new dimension to the technology. The Imhoflot G-Cell has …

It is suggested to use extra …
Apart from the entrainment of normal fine particles during flotation, clay minerals with a particle size normally smaller than 5 μm also undergo aggregation, generating aggregate structures which compound the entrainment problem. The aggregation behavior of clay minerals is attributed to their complex crystal structure, …
A 2 m diameter REFLUX™ Flotation Cell was fed at roughly 210 m 3 /h, equivalent to a flux of 1.9 cm/s, about twice the maximum rate used in conventional flotation cells. The coal feed slurry had 59–64 wt% head ash and nominal size range −0.100 mm (Sauter mean size 0.004 mm).
Imhoflot TM flotation was introduced to the mining industry more than 25 years ago by Maelgwyn.
