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.

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
