✦ Synopsis

The infrequently reported fish hook in hydrocyclone classifiers has been ignored by many or disputed due to its random and sporadic occurrence. The imprecision of measurement of the actual efficiency and the 'uncertainty principle'/observer effect appear to be main factors in its evolution and partial acceptance. Significantly, fundamental models to date do not predict a fish hook. Current theories to explain it based on size dependent bypass mechanism are mere mathematical transformations. It may be of theoretical/academic interest only as its exclusion in simulation models does not appear to affect cyclone performance prediction. This paper attempts to show that it is still a long way before it could be universally accepted as a scientifically significant physical effect.
