Hydrocyclones are ideal for recovering down to 400 mesh 38µm particles of 2.7 SG. This is typically done in the form of an Ultra Fines Recoveryprised of a Sump, Pump, Cyclones and Dewatering Screen, which will have a discharge to waste nominally 90 passing 400 mesh 38µm and a product discharging the screen in a drip free, readily conveyable and stackable form.
