Hydrocyclones are used in industries such as mining, minerals processing and aggregates to classify, densify, dewater, de-slime and recover fines. What is a hydrocyclone in mining? The mining industry makes use of hydrocyclones to separate coarse and fine particles, according to the size and density of the particles.

In most mineral comminution circuit, the feed to the hydro cyclone classifier is composed of a mixture of particles having varying degrees of liberation and sizes. ... Classification is conducted at various stages in the enriching process. Hydrocyclones can be used in the classification of a number of mineral raw materials (e.g. ores of copper ...

The mineral processing industry uses hydrocyclones in this way. It also uses them as heavy media separators where the liquid density is increased to be intermediate between a light mineral and a heavy mineral. The light then passes to the overflow, the heavy to the underflow. Applications extended to the chemical and food industries.
