Abstract. In recent years Coal Preparation Plant designers globally are increasingly considering large diameter Dense Medium Cyclones (DMC) for treating the full size range of feed, in preference to a combination of open Bath or Drum Dense Medium Separators (DMB) and DMC's. The system is used successfully on most dense medium separation plants today and with proper configuration can maintain densities accurate to the third decimal. The plants have excellent standards of electrical installation and high lux level internal and external lighting for good night time visibility both on and around the plants.

Density Gradient Media Overview - Stemcell Technologies

Density gradient centrifugation is commonly used for the isolation of specific cell populations from whole blood. This technique takes advantage of the differences in density between the various leukocytes and the density gradient medium. As a result, the particular cell populations isolated will depend on the density of the medium that is used. Heavy Media Gravity Separation Heavy media gravity separation involves using a mixture of fine media material, such as magnetite (SG 5.1) or ferrosilicon (SG 6.8), suspended in a slurry of water, to produce a media slurry with a specific gravity that will allow low density material(s) to float, and other high density material(s) to sink.
