Batch centrifugal concentrator's provide high concentration ratios, >1000:1 typically, but operate with relatively low stage recoveries of 20-40%. They rely on the efficiency of the cyclones to retain GRG within the grinding circuit
1. Introduction. This chapter describes units, circuits, and strategies used to recover gold that is either liberated or present in very high-grade gold particles, referred to as gravity-recoverable gold (GRG), as well as gold present in much lower grades in sulfidic particles, typically pyrite and arsenopyrite, that can in their own right be recovered by …

Under the action of centrifugal force, heavy minerals are stacking on the inner plate groove of the rotor core, and the light ore particles are gradually discharged. After about 4-6 hours of operation, stop feeding, and turn on the backwater to wash out the gold concentrate. Gold centrifugal concentrator is useful in the gold recovery in all ...
