In 1858 Sir Henry Bessemer patented a coal cleaning process using a cone shaped vessel and salt as the separating medium. Since then different vessel shapes and …
The cyclone is a piece of equipment which utilizes fluid pressure energy to create rotational fluid motion. This rotational motion causes relative movement of the materials suspended in the fluid, thus permitting separation of these materials from one another.
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.
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.
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.
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

The dynamic, multi-stage Condor Dense Medium Separator gives Sepro a leading position in advanced Dense Medium Separation (DMS) technology. A minimum of two separation stages are inherent in a Sepro Condor DM Separator, resulting in high separation efficiency in rougher/scavenger or rougher/cleaner DMS applications. DMS is typically used in a pre-concentration duty prior to …
Dense medium cyclones 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 ...
A computer simulation system for the dense-medium cyclone separation process has thus been established. The paper presents the results of the simulation study of the intelligent control system and also the initial results of the industrial test of it.
Dense medium cyclones are used for very accurate separation of particles of different density. Particles smaller than 0.5mm are removed from the mixture before it enters the cyclone.

Dense Medium Drum and Cyclone Plant. The Parnaby Dense Medium Drum and Cyclone Plant is a washing plant which enables customers to process a range of different feed material in the coal preparation industry.
Condor Dense Medium Separators provide a simple, cost-efficient way to separate and recover valuable minerals at a coarse particle size, ranging from as fine as 0.5 mm to as coarse as 50-70 mm but typically in the range of 1- 50 mm. Dense medium separation technology is used for a wide range of mineral separations to produce premium concentrate.
Dense medium separation (DMS), synonymous with heavy medium separation (HMS), is a form of gravity concentration technology involving float-sink separation that historically has been used predominantly in the coal and diamond processing industries.
The most common process factors that affect Dense Medium Cyclone (DMC) performance can be mitigated by understanding the operation of a hydrocyclone, as well as the overall Dense Medium Separation (DMS) process.
The density at which 50% of the particles report to sinks is shown as the effective density of separation, which may not be exactly the same as the medium density. The lower the, the nearer to vertical is the line between 25 and 75% and the more efficient is the separation.
A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.

Additional separation of the denser material occurs by centrifuge in "cyclones" that swirl the mixture at low and high speeds, forcing the diamonds and other dense minerals to the walls and then out the bottom of the cyclone. Waste water rises at the center of the cyclones and is sucked out and screened to remove waste particles. The DMS process results in a concentrate that generally ...
