A material extraction nozzle for separating a mixture of materials having different densities, comprising: a nozzle body shell having an outer surface with a tangentially located material inlet at an upper portion thereof and an inner surface defining in part a frustrum of a cone; a substantially conical diffuser section having an outer surface terminating in an apex, the diffuser section axially aligned within the nozzle body shell in a spaced relation therewith so as to form an extraction chamber with the inner surface of the nozzle body shell and the outer surface of the substantially conical diffuser section; an extracted material outlet port positioned axially through the substantially conical diffuser section; and at least one rejected material capillary outlet located below the apex of the diffuser section.
