Hydrocyclone Wikipedia
Hydrocyclones are a type of cyclonic separators that separate product phases mainly on basis of differences in gravity with aqueous solutions as the primary feed fluid. As opposed to dry or dust cyclones, which separate solids from gasses, hydrocyclones separate solids or different phase fluids from the bulk fluid. A h

Wills' Mineral Processing Technology, 8th Edition
Classification. Classification, as defined by Heiskanen, is a method of separating mixtures of minerals into two or more products on the basis of the velocity with which the particles fall through a fluid medium. The carrying fluid can be a liquid or a gas. In mineral processing, this fluid is usually water, and wet classification is generally
