Gravity Recovery of Gold From Within Grinding Circuits

Batch centrifugal gravity concentrators, which produce very high concentration ratios, have become the devices of choice for recovering gold from within grinding circuits. These are usually installed in the mill discharge, cyclone feed or the cyclone underflow streams where a fraction, typically 10-40%, of the stream is treated by the gravity circuit.
