Minerals | Free Full-Text | On Limits to Flotation Cell Size
Mechanical cells have seen an exponential increase in size over the past 60 years. However, a possible size limitation due to carrying capacity constraints has been raised. Taking a Cu porphyry case, a cell sizing exercise is used to show that possible size limitation due to carrying capacity can be tested using available techniques. A range of …
DR flotation machines
In principle, the cell functions as a shallow flotation cell. As the air and pulp are hydrau-lically lifted to the top of the pulp recircula-tion well, the mineral laden air bubble has only to travel a short distance on its own to the froth overflow level. Above are illustrations of three flotation cells. 14.2 m3 (500 cu.ft) cell 2.8 m3 (100 cu ...

Optimizing Flotation Cells
Flotation Cells (Froth Flotation) were developed to separate and recover high value Sulphide ores from low grade ore bodies. The ore is crushed and milled at the concentrator in a process known as comminution, where the mineral is in suspension in slurry. The particle size for mineral being recovered is generally less than <0.1mm.

Improving flotation energy efficiency by optimizing cell hydrodynamics
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.

A novel scale-up approach for mechanical flotation cells
Gorain et al., 1997a, Gorain et al., 1997b and Alexander et al. (2000) suggested the use of the bubble surface area flux as the scale-up criterion by considering a linear relationship with the flotation rate. This approach was tested for cells over 50 L, where they believe the hydrodynamic effect (turbulence) to be less significant.
