The dense medium cyclone – past, present and future

Since the dense medium cyclone (DMC) was first patented in the 1940s it has become the process of choice in coal preparation, and is also widely used for upgrading iron ore and in the pre-concentration of diamonds and metalliferous and industrial minerals. It is in every sense a mature technology.

The dense medium cyclone – past, present and future ...

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 lower heads, as in coal preparation. The DMC can compete effectively as a process of choice ...

The effect of cyclone geometry and operating

Dense medium cyclones separate particles primarily according to their differences in density, and are used in the beneficiation of coal, iron ore, and diamonds, amongst others. The cyclone can, however, be constrained by the ore carrying capacity of the spigot, especially for ores in which a significantly large proportion of the feed particles ...

Prediction of Underflow Medium Density in Dense

Abstract. The prediction of the underflow medium density, ρ u, in a dense medium cyclone is important, both because many empirical and phenomenological models of DMC performance incorporate ρ u as an independent variable, and for plant design purposes. This paper reviews the published correlations for ρ u, and presents some recent work on the subject.. Three approaches have been used ...
