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.
