Cyclone technologies for efficient size mass and density …
"When multi-density particles enter the mix, then a hydrocyclone, in essence, separates based on mass. With homogeneous ores, mass and size are directly related, because bigger particles always have bigger mass, so we can still use the term cut-size to describe the separation process. But when the densities are different, this is not the case.
Function and applications of hydrocyclones

How to Fix Common Issues with Hydrocyclones
Replace hydrocyclones with a smaller quantity of larger diameter hydrocyclones; Laying a hydrocyclone on its side, to a 45-degree angle or even down to a 15-degree angle from horizontal can significantly increase the cut size; Increase the density of the feed (especially at high densities) Troubleshooting Dewatering Hydrocyclones
HYDROCYCLONES
The size and shape of the vortex finder, the shape, of the chamber into which the feed liquid is injected and the geometry of the feed inlet all dictate the details of the flow pattern which will often include recirculatory streams (see Figure 5)..
