Jameson Cell has accurate scale-up reliability and is the real-word specification in any and all duties within a flotation circuit: rougher and scavenger duty; cleaner and cleaner scavenger duty. In fact, a single Jameson Cell has successfully replaced a traditional circuit of cells; and unlike other competing cells, it has no moving parts.

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).

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 …

Specifically designed to maximise fine particle recovery, the Dorr-Oliver flotation cell is the most energy efficient, technically advanced, forced-air flotation machine on the market. Its air dispersion capabilities exceed all competitive forced air designs – an important consideration for fine particle recovery.

The study of flotation hydrodynamics is, however, a complex task due to the nature of flotation systems, which are opaque, multiphase, and polydisperse. In this paper, the impact of impeller design modifications on the hydrodynamics of a flotation cell was quantified for the first time in a three-phase system.

In order for flotation cells to perform effectively, these requirements have to be met and thus optimal use of energy is critical to the process. The distribution of the energy dissipation rate within a flotation cell determines both the capture of ultrafine particles (high shear) and the detachment of coarse particles (low shear) (Jameson ...
