The dense medium separation process (DMS) is a mature technology, and is widely used in mineral and coal processing. The dense medium cyclone (DMC) is the most ubiquitous of the DMS vessels in use, and deservedly so. It is efficient (when run properly), can process both coarse and fine sizes, and has a relatively small footprint.

Cyclone plants quickly became widely used in Europe, but the first United States plant was not built until 1961. Several different configurations are available, the standard cyclone is available from several vendors, either as individual cyclones or as complete separating systems.
Modular dense medium cyclone plants 2 FL supplies a comprehensive range of modular Wemco® Dense Media Cyclone Plants utilising either Wemco ® or Krebs HM Cyclones. Wemco systems are installed and operating on many different minerals ranging from coal, manganese, magnesite, right through to fluorspar, iron ore, and diamonds.
Centrifugal separators in the form of the cyclone DM separator are widely used in the treatment of ores and coal. DM cyclones proved a high centrifugal force and a low viscosity in the medium enabling much finer separations to be achieved than in gravitational separators (Wills, 1997).
of the dense-medium cyclone for washing down to 0,075mm.Sokaski andGeer12havemadesimilar reports, and Mengelers and his co-workersI3,14 have produced several papers onthissubject. In1957,theDutch State Minesand Coppee designed andbuilt twodense-medium cyclone plants inBelgium, at Tetre and Witerslag, which treated afeed smaller
The dense-medium or the magnetite suspension, in which the separation takes place, also has a significant impact on the efficiency of the cyclone. The stability and rheology of dense-medium suspensions have shown to influence the performance of the process.
Dense medium cyclone operation is very sensitive to the variation of process and design variables. The author and his co-workers have developed simple empirical models to predict and optimise the performance of dense medium cyclone. The usage of these models developed at the laboratory level to improve the plant performance has been discussed.
