Dense medium cyclone (DMC) is widely used in modern coal preparation industry to upgrade ROM coal because of its ability to achieve sharp separations and high capacities at the same time [4]. Therefore, monitoring and control for this circuit is critical for the productive and financial performance of a coal mine [5].

•The Dense Medium Cyclone is now the worlds most commonly used Coal Preparation Separation Process •DMC’s are also being increasingly being used on Mineral Applications •Large Diameter High Capacity Units are now the Norm •There is renewed interest in Fine Coal Dense Medium Separation to produce high value products.
Advances in Dense Medium Cyclone Plant Design …
In coal preparation, large dense medium cyclones (DMC) at low pressure heads (typically 9D where D = cyclone diameter) are the norm. This contrasts with high density mineral applications where, largely for historical reasons, smaller cyclones at high heads are the standard. There are advantages in preferring large diameter cyclones at low heads, assuming that...

DENSE MEDIUM CYCLONE OPTIMIZATON …
Dense medium cyclones (DMCs) are known to be efficient, high-tonnage devices suitable for upgrading particles in the 50 to 0.5 mm size range. This versatile separator, which uses centrifugal forces to enhance the separation of fine particles that cannot be upgraded in static dense medium separators, can be found in most modern coal plants and in a variety of mineral plants treating iron ore, dolomite, …
Dense Medium Cyclone Handbook - acarp.com.au
Dense medium cyclones were introduced into Australian washeries in the 1950s. Modern circuits continue to be based on the strong foundations provided by the Dutch State Mines and Stamicarbon BV, but over the ensuing decades, many innovations have been trialed. Many have been rejected and others have proven useful and have been widely adopted:
The dense medium cyclone – past, present and …
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.
Dense-Heavy Medium Separation HMS / DMS …
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 the heavier shale or high-ash coal.
Gravity Feed Three Product Dense-Medium …
The 3NWX dense medium cyclones are capable of not only separating coal particles but also concentrating and the heavy media at the same time, which makes it possible to use single low density heavy medium, instead of using both low and high densities, to produce three qualified clean, middling, and reject products at one time.

Dense Medium Cyclone Metallurgist & Mineral Processing. From the early 1960’s until the mid 1980’s, dense medium cyclone circuitry design technology did not change appreciably. The basic design, which was both highly flexible and highly efficient, was consistent with technology developed by the Dutch State Mines (“DSM”) in the mid 1940’s.
