PRACTICAL OPERATIONAL ASPECTS OF DENSE MEDIUM CYCLONE SEPARATION F Bornman Multotec Process Equipment (Pty) Ltd 28 Forge Road, Spartan Kempton Park, 1620, South Africa (Author: [email protected]) ABSTRACT Reeves and Platt1 stated that dense medium separation … Washery-II of West Bokaro, Tata Steel, India has eight cyclones in a bank treating medium coking coal in the size range of − 13 + 0.5 mm. A three-mode strategy was adopted for increasing the clean coal yield from the washeries. Efforts were made initially to determine the major performance indices that would be used for measuring the separation efficiency.
The medium density determines to a large extent the density at which the separation will take place, and is the main variable available to the operator for controlling separation. In static bath separators, such as drums and cones, the separating density (or cut-point) is generally close to the medium density.

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.
Dense Medium Separation method is a Mineral Processing Method, which is being used to separate the ore samples into a series of fractions according to density, establishing the relationship between the high and the low specific gravity minerals. The dense medium cyclone (DMC) process used in coal beneficiation plants is studied from a control system perspective. Employing the dynamic model of the DMC process derived from mass flow balance ...

Coal Preparation, natural moderate washing plant - Mining … Dense medium cyclone- only plants could be supplied for cleaning small coal beneath 50mm particle dimension. ...
Dense-medium beneficiation of fine (minus 0.5 mm) coal is not a new concept and has been used in South Africa previously. The dense-medium fine coal plant at Greenside Colliery operated for almost 18 years and, despite proving a difficult plant to operate, did succeed in producing a fine coal product with a low ash content of 7%. No other ... The over-dense medium is returned to the over-dense medium sump and distributed to the dense-medium washing circuits as make up. Magnetic separator tailings are used as product rinsing water. Considering the overall economics of steel-making, it was thought to reduce the composite clean coal ash at the washeries from 17% to 16% starting April 2003.

Step 7: Feed Medium Density Check. To check the selection of the feed medium density was correct, which was based on an approximation of the difference between the required separation density and the medium density, the following expression is utilized:ρ50= ρm +0.125+0.154 ρu-0.215 ρo = 1.29+ 0.125 +0.154(1.54)-0.215(1.20) = 1.39
The medium density at which the separation between more dense and less dense material occurs is called the cut point density.

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.
