TECHNIQUES FOR OPTIMIZING PERFORMANCE OF CYCLONES

Apparatus is provided including a signal processor or signal processing module configured at least to: respond to signaling containing information about particle sizes of solids forming part of a slurry stream being fed with a common feed flow into a battery of cyclones; and determine which combinations of cyclones in the battery produce overflow that has undesirable particle size characteristics using a statistical algorithm or technique, based upon the signaling received. The signal processor or signal processing module provides corresponding signaling containing about which combinations of cyclones in the battery produce overflow that has undesirable particle size characteristics, including control signaling to control the operation of the battery, including information about certain combinations of cyclones to avoid, or preferentially to use, to minimize the total amount of coarse material having the undesirable particle size characteristics produced by the battery.
