AMIT 145: Lesson 3 Dense Medium Separation
Density of Water = 1000 kg/m 3; 1 m 3 of Water = 1000 kg. Magnetite Density = 5170 kg/m 3. [image 145-3-29] [image 145-3-30] For example, a 400 tph feed to a dense medium process equates to a volumetric flow rate of 1000 gallons/min or 3.785 m 3 /min. At a 4:1 medium-to-coal ratio, the volume of medium is 15.14 m 3 /min.
Effect of operating variables on the performance of dense-media cyclone
In a coal washery, two or more dense-media cyclones (DMCs) are normally connected in parallel to form a bank sharing a common feed pipe. Depending on the operating and design variables and on the wear and tear of the equipment, the efficiency of the cyclones would vary. Efforts were made at Tata Steel's R&D Dept. to evaluate the …
Heavy Media Separation Process
The heavy-media separation process, or HMS, employing ferrous media, usually ferrosilicon and/or magnetite, is the most generally used process for sink-float separations. A stable medium over the range of specific gravities from 1.25 to 3.40 can be maintained within close limits and is cleaned and recovered by magnetic means.

AMIT 145: Lesson 2 Classifying Cyclones
Krebs Engineers approach cyclone design similar to screen design. Cyclone design is based on the d50(c) achieved using a typical cyclone under standardize conditions, i.e., Medium = water at 20 °C & 1 centipoise; Solids density= 2.65; Solids concentration < 1%. Pressure drop = 10 psi. The base d 50(c) can be estimated by the expression:

Separating Density
Heavy medium cyclone is different from a classifying cyclone with its horizontal orientation, a larger inlet diameter, relative to the cyclone's diameter and operating with lower head. It has become nearly universal in the cleaning of (100 mm×12.5 mm) coal and (12.5 mm×0.5 mm) in dense medium cyclones.
Dense Media Separation (DMS) Plants
Dense Media Separation. A heavy medium is a heavy-fluid or heavy suspension fluid with a density greater than that of water (1g/cm3). The process of separating ore particles in heavy media is called Dense Media Separation / Heavy Media Separation (DMS / HMS). The heavy medium separation method is an advanced gravity beneficiation method.
Conventional and recent advances in gravity separation
Two types of cyclones are used in gravity separation of coal cleaning: dense medium cyclone (DMC) (Fig. 8 c) and water-only-cyclone (WOC). DMC is costlier than WOC but can achieve sharper separations than WOC, making it suitable for cleaning coal containing gangue minerals with similar density as coal.
