The slurry flow then enters the feed end of the flotation cells. The slurry at this point is called the HEADS of the circuit. The mineral is then separated and flows over the overflow into a trough called a flotation cell LAUNDERER. The OVERFLOW is now called the flotation CONCENTRATE of the circuit.

For example, Glencore's McArthur River Mine produces a concentrate at a P80 of 7 µm (Pease et al., 2010). Processing plants using conventional flotation technologies and fine/ultrafine particle size typically struggle due to poor hydrodynamics to recover fine liberated particles (Jameson, 2012). This paper proposes the Jameson Cell as a ...
