In these equations, c is the solids concentration, c 0 is the solids concentration in the feed, and is the mean retention time of the suspension. Comparing the above equations shows that theoretically a plug flow flotation cell is more efficient than a perfectly mixed system (for the same k and ); to put this another way, a smaller plug flow …

However, the physics of traditional flotation cells presented a constraint in the use of these reagents to achieve flotation of these particles. Over the past two decades, flotation cell manufacturers have cleverly overcome some of those physical limitations and have designed cells that can float particles >300 μm efficiently.

The essence of a fluidized bed flotation cell is a three-phase fluidized bed. In a three-phase bed, a bed of solid particles is suspended in the liquid and gas phases to produce close contact, which may be in a parallel or counter-flow manner [51]. When the fluidized bed expands upward under the net buoyancy of the solid particles, it is termed ...

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).
