The Reflux Classifier offers a significant throughput advantage over more conventional fluidized bed separators, estimated to be up to 50-fold when targeting the recovery of particles with a density of 4000 kg/m 3 down to a particle size of 10 μm.

A reflux classifier or a reflux flotation cell may require many lamella plates to effectively make the intended separation of a high-throughput slurry. In some cases, a separator may include up to around 3300 (rc3000 takes 3328 plates) lamella plates or even more, representing around 2.5 miles of plates that are around 9.4 inches wide.
