Oct 22, 2016· 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.

Fine coal processing with dense medium cyclones

not been nearly as successful as in the processing of coarser coal. There is a perception in the coal processing industry that dense-medium cyclone processing of fine coal is expensive, that it consumes much magnetite and that the separation efficiency is not …

Mineral processing - Wikipedia

Industrially, the most common dense media is a suspension of fine magnetite and/or ferrosilicon particles. An aqueous solution as a dense medium is used in coal processing in the form of a belknap wash and suspensions in air are used in water-deficient areas, like areas of China, where sand is used to separate coal from the gangue minerals.

Dense Medium Cyclone -

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. During this period, the "typical" dense medium cyclone circuit was designed to process raw coal ...

Dense-Heavy Medium Separation HMS / DMS Process

HMS and DMS are acronyms for Heavy (Dense) Medium Separation and is applied to the process of pre-concentration of minerals – mainly the production of a high weight, low assay product, which may be rejected as waste. In principle it is the simplest of all gravity processes and is a standard laboratory method for separating minerals of different specific gravity.

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 media separation (DMS) plays an integral part in coal processing as well as in the upgrade of low grade ore bodies prior to further processing like flotation and leaching. Various separating vessels are used in DMS; of which the dense media (DM) cyclone is the most common.

Process description – DMS cyclone plants. The DMS process involves the mixing of a pre-prepared ore stream with a dense medium of selected specific gravity (SG) in a mixing box and passing this mixture through a dense medium cyclone (DM cyclone). It is here that separation of the high and low SG fractions of the ore occurs.

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.
