ABSTRACT OF THE DISCLOSURE CENTRIFUGAL SEPARATOR A centrifugal separator for extracting heavy metals from a slurry comprises a centrifuge bowl (30) having an inwardly facing surface over which the slurry runs. A dam at a discharge end of the surface forms a shallow layer (55) of particles which separate preferentially the heavy metals. The surface includes a portion formed by a plurality of annular membrane portions (44) spaced axially and separated by radial rings (42) extending from the surface to a supporting metal bowl (36). The membranes are deflated or retracted to gradually form annular cups for receiving the separated metals. The membranes are then inflated to discharge the collected materials while the feed is temporarily halted and the bowl continues to rotate.
