Gravity separation of ultra-fine iron ore in the REFLUX™ Classifier
This paper reports tests performed on an ultra-fine iron ore with nominal top size of 0.106 mm, but with 59 wt-% being below 0.038 mm in size. The REFLUX™ Classifier consists of a set of parallel inclined channels positioned above a vertical fluidised section.

Performance of the reflux classifier for gravity separation at full scale
Again, it is evident the separations produced using the pilot-scale and the full-scale Reflux Classifier are very similar. The higher E p for the full-scale RC in the finest size fraction is a consequence of having used a higher maximum density bath in the sink-float analysis, which gives rise to a higher upper limit. (Note the curve is just ...
