Dense-medium cyclones have been used for many years in a number of countries around the world to beneficiate fine coal. The use of cyclones in this application is, however, not widespread and at present, the process is employed only in South Africa and China.

Dense medium (sometimes called heavy media) cyclones were developed during World War II by the Dutch State Mines. The original application was for coal cleaning. A cyclone pilot plant was successfully operated in Europe during 1945, and observed by H. F. Yancey of the US Bureau of Mines (USBM, now part of the Department of Energy (DOE)).
Hence the GTech® Dense Medium Cyclones from HMA Wear Solutions are designed to exceed industry expectations. The advantages of the GTech® Dense Medium Cyclone from HMA Wear Solutions includes superior cyclone and lining design, a high separation efficiency, optimal ceramic selection, reduced operating costs, engineered tiles and monolithics, and ongoing technical support.
Dense medium cyclones are used extensively in the minerals processing industry around the world and cyclones with larger diameters have been introduced in recent years. Although cyclones have been in use for well over 60 years, the influence of the different process variables such as cyclone dimensions, feed pressure, medium properties and feed rates are not yet fully understood.

Dense-Medium Cyclones (DMC) Dense medium cyclones (DMC) have been found to be effective in treating particle size fractions between 3-inch and 100 mesh, however, not typical done in a single unit. The DMC application for treating 16 x 100 mesh material is limited due to significant magnetite loss resulting from inefficiencies on the drain-and-rinse screens.
cyclones. Furthermore, the slurry mixture of the heavy medium utilised for the purpose of dense medium separation should be non-detrimental to the effectiveness of separation in the DMS Fine cyclone plant. Medium characterisation showed that removal of ultra-fines leads to unstable media as indicated by faster settling rates.
Dense medium cyclones (DMCs) are widely used coal-cleaning devices in the mining industry. For hard-to-clean (+10% near gravity material) in the size range of 50 mm to 0.5 mm, DMCs are very effective. In operation, the raw coal and the medium are fed at a precise pressure into the tangential inlet. The ensuing flow spirals towards the apex of
Dense medium cyclone is a kind of device which utilizes centrifugal force to separate materials according to specific gravity in the medium. The raw material to be treated is suspended in a very fine medium. The pulp is fed to three product dense medium cyclone through the inlet to short cylindrical section by the force of gravity.
dense medium cyclone simulations assumed that the medium solids had a density of 5000 kg.m-3 and a single particle size of 30 µm (typical for magnetite). The classifying cyclone simulations assumed the particles were coal with a density of 1350 kg.m-3, however a feed
The dense medium cyclone is a mature and efficient process. • The behaviour of the medium is process-determining. • Semi-empirical models exist which can be used for process design and optimisation. • Economics will be greatly improved with larger cyclones and

Abstract. Cyclones have been in mineral processing since the first patent in 1912 and amongst the many uses of the configuration of the cyclones is the DENSE MEDIUM CYCLONE, used for separation of particles of different densities; separation enhanced by the use of either magnetite or ferrosilicon as an essential element of the process to create the desired effect.
To keep dense-medium cyclones in ideal working conditions, there are a number of important factors to keep in mind in the day-to-day operation of coal dense-medium processing plants. Bornman explains that one such factor is that mines should ensure that there is proper oversize protection from foreign objects – e.g. steel – in the case where ceramic lined cyclones are used.
