A multi-stage gas-solids separator having at least 4 stages is configured so that the penultimate stage of separators is operated in an underflow condition. The underflow from the penultimate stage is used as the input flow for the final stage of separators. The multi-stage separator is preferably composed of cyclone separators, with the final two stages of separators housed in external disengaging vessels.
