In this case, cyclone underflow is fed to a ed area in the underflow tub, and gravitycircuit feed taken from this area. Slurry excess to the capacity of the gravity circuit overflows back to ballmill feed. For those circuits treating ballmill discharge, a sluice can often be arranged to provide some preconcentration for the gravity circuit.
