Experiments conducted with a 75-mm-diam hydrocyclone have shown it is possible to obtain an iron ore concentrate containing 60% Fe, 2.65% SiO 2 and 4.0% Al 2 O 3 from Barsua iron-ore washing-plant slimes. About 60% of the iron values are recovered from slimes containing approximately 49% Fe, 8.9% Al 2 O 3 and 11% SiO …

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 Recovery system comprised 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, …
