At rougher and scavenger rougher steps; the solid flowrate increased from 1.000 to 1.243t/h and the solid concentration decreased from 35 to 30.47%. Consequently the residence tines decreased from ...

Jameson Cell

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.
