Abstract: A dewatering system (12) for dewatering a slurry discharged from a riser (4) in a hydraulic ore hoisting system (10) to provide a driving fluid for use in said hydraulic ore hoisting system is described. The dewatering system comprises a primary cyclone (20) and a dewatering screen (26) for receiving a primary cyclone underflow stream (24) and having at least one upwardly sloping vibrating screen deck to create a lateral flow (38) from the underflow stream over the raised end of the deck and a vertical flow (36) from the underflow stream through the screen deck. The dewatering system also comprises a secondary cyclone (50) for receiving a combination of the primary cyclone overflow and the dewatering screen underflow to concentrate the remaining fine particles into a secondary cyclone underflow stream (54) to be recirculated to the vibrating screen deck of the dewatering screen, and a secondary cyclone overflow stream (52) suitable for use as a driving fluid.

Abstract: Apparatus for a cyclone separator are disclosed. A collection tray (50) for an abatement apparatus cyclone separator (10) operable to separate particles from a processing tool effluent stream, the collection tray comprising: sidewalls; and an inclined floor positionable to receive the particles from a plurality of cyclone separators (30) locatable above the collection tray and to convey the particles to a drain aperture. In this way, the accumulation of particles in the vicinity of the cyclone separators is reduced which helps to prevent the operation of the cyclone separators from being impaired.
