Two different flotation cells were used for this purpose, i.e. a Hallimond tube and a subaeration cell (Denver D-12).
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 ...

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.
Hydrodynamic conditions such as gas dispersion, mixing intensity and solids suspension are known to govern the metallurgical performance of the flotation process. Understanding flotation cell hydrodynamics is therefore important for the optimisation of existing cells and for the design of the larger and more efficient cells which are needed to handle the finer, …

This is a flotation equipment in which high-speed ore slurry and air are mixed and mineralized in the spraying device, and the separation is realized in the cell. It can be divided into air suction type and compressed air type. (1) Typical air suction flotation cell is China FJC jet flotation cell series.
Mechanical flotation cells can be broken down into two broad categories based on how air is introduced to the cell. In a self aspirated flotation cell air is introduced to the slurry, the vacuum created by the rotorusing . In a forced air flotation cell air is generated external to the cell by a low pressure blower,, and pumped down the

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).
