Abstract
The cyclone is widely used in the taconite industry to close grinding circuits. For a given
cyclone geometry, the main operating variables are flowrate, feed size distribution, and slurry
rheology. Generally the slurry density (percent solids) is used to approximate the slurry
rheology. However, it is known that slurry temperature can also affect the rheology. The
purpose of this test program was to determine the effect of temperature on cyclone performance
as measured by cyclone weight split and cut size, D50• Two samples of cyclone feed were
obtained from Evtac (now Utac). The samples were taken about 6 months apart.
