It has now been proven to have a higher potential than traditional cells in coarse particles flotation [48,49]. The fluid-like state in which the particles appear in operation through contact with both the gas and liquid phases becomes fluidization [50]. The essence of a fluidized bed flotation cell is a three-phase fluidized bed.

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 …

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 …

Highest recovery rates. For decades, WEMCO flotation cells have consistently delivered the highest recovery. WEMCO II's combination of efficient aeration and optimum solids suspension not only increases recovery and concentrate grade performance, but also reduces reagent consumption.

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 research to date has identified two main reasons for the upper limit on floatable particle sizes. First, coarser particles tend not to have as ...

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.

In its essentials, a flotation cell must provide for two main functions. First, it must supply air adequate in quantity and quality for satisfactory process kinetics. Air quantity can be defined on the basis of the narrow range provided in major U. S. commercial cells, for escape velocity, which averages near 1.2 m/min (4 ft /min).

In turbulent flotation cells, the velocities of particles and bubbles are independent of one another and are functions of the local energy dissipation rate (Schubert and Bischofberger, 1979) as follows: 0.4 84/9d~/9 (pi - pf 12/3 Ui - v1/3 k.TJ (2) where e is the turbulent dissipation rate per unit mass and time (in W/kg or m2s-3 units), v is ...
