Chapter 11 Dense Medium Separation (DMS)

Introduction Dense medium separation (or heavy medium separation (HMS) or the sink-and-float process) is applied to the pre-concentration of minerals i e the rejection of gangue prior to grinding for final liberation It is also used in coal preparation to produce a commercially graded end-product clean coal being separated from

HYDROCYCLONES

The centrifugal force that is generated is capable of separating particulate solids down to around 5 to 10 microns in size The smaller the diameter of the cyclone the higher the force and the higher the efficiency of separation of small particles Long cone designs also exist which claim to give good efficiency with particles of less than 5 microns

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
