Further, the experiments are continued with iron ore slimes. The novel hydrocyclone is able to provide desired cut size and sharpness of separation required to separate iron from alumina and silica. It also enhances the classification by reducing coarse and fine particle misplacement compared to the conventional hydrocyclone design.
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, …
