Hydrocyclone

A hydrocyclone (often referred to by the shortened form cyclone) is a device to classify, separate or sort particles in a liquid suspension based on the ratio of their centripetal force to fluid resistance.This ratio is high for dense (where separation by density is required) and coarse (where separation by size is required) particles, and low for light and fine particles.

Hydrocyclone Operation Mineral Processing amp; Metallurgy

The hydrocyclone operation consist of having the ore slurry pumped into its feed inlet, the ore is then separated by size with the fine material coming out of what is referred to as the OVERFLOW via a Vortex Finder. The mineral that still requires grinding is named the UNDERFLOW via the Apex Finder. These two terms, the overflow and underflow will become very familiar
