Performance of a new centrifuge (Falcon) in concentrating a gold
Abstract The gravity treatment of fine minerals has experienced a promising advance with the introduction of centrifugal concentrators in the market, particularly to recover fine gold, as is the case of, for example, the very well known The machines utilise the principles of a centrifuge to enhance the gravitational force experienced by feed particles to effect separation based on particle density The key components of the unit are a cone shaped "concentrate" bowl, rotated at high speed by an electric motor and a pressurized water jacket encompassing the bowl Feed material, typically from a ball mill discharge or cyclone underflow bleed, is fed as a slurry toward the centre of the bowl from abovKnelson concentrator
