Dense Medium Cyclone - Metallurgist & Mineral …
A typical dense medium type coal preparation plant included dense medium vessel circuitry for the “coarse” raw coal, dense medium cyclone circuitry for the “intermediate” size fraction with a spiral (or water-only cyclone) circuit for raw coal down to about 0.15 mm Ultra-fines (0.15 mm x 0) were either discarded to refuse or processed in froth flotation circuits.
Fine coal processing with dense medium cyclones
dense-medium cyclones in the processing of fine coal and reviews some of the important considerations for successful application of the technique. INTRODUCTION The dense-medium cyclone has, since its development by the Dutch State Mines almost 70 years ago, become the main processing unit in the coal industry. It is capable

and the sharp rising energy price. Dense medium cyclones (DMCs) are used as the main coal bene cation process in modern coal washing plants because of their high capacity and e ciency (Chu et al., 2009). The relative density of the dense medium used to enhance the separation is the key factor that a ects the quality of coal after this DMC circuit.

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 stone reviews the published correlations for ρ u, and presents some recent work on the subject.. Three approaches have been used ...
Dense Medium Cyclones: International Journal of …
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.
