Effect of dense medium properties on the separation performance of a dense medium cyclone

Minerals Engineering, 1994
Extensive separation tests were carried out on a 6″ dense medium cyclone loop with the use of density tracers to study the effects of medium stability and rheology on the separation of fine particles. The medium properties were modified by changing the magnetic particle size and medium density. Four magnetite samples with RRB size modulus d63.2 ranging

Dense Medium Cyclone Separation of Fine Particles Part 2. The Effect of Medium Composition on Dense Medium Cyclone Performance

Coal Preparation, 1995
The effect of medium composition on dense medium cyclone performance is investigated. It is found that a change in composition affects medium stability and rheology, and may lead to different responses in separation efficiency and cutpoint shift. The final result depends on whether the medium stability or rheology is the dominant factor, and also on ...

The Influence of Near-Dense Material on the Separation Efficiency of Dense-Medium Processes

International Journal of Coal Preparation and Utilization, 2008
Near-dense (also termed near-gravity) material is material that has a relative density that is close to that of the separating liquid or dense medium used to separate coal and the impurities contained in raw coal. Near-dense material makes the separation more difficult because it settles very slowly in the dense-medium due to the fact that its density ...

Dense medium separation in an inverted fluidised bed system

Minerals Engineering, 2018
Abstract The purpose of this work was to examine the novel concept of performing a wet dense medium separation, utilising magnetite, on a fine (−1.0 mm) coal feed in an inverted fluidised bed system. The feed was a natural mixture of coal and mineral particles and the fluidised bed system was an Inverted Reflux Classifier.

Medium circuit design and control for multi-density dense medium separation plants

, 1994
The paper describes the new design criteria and control strategies for multi-density dense medium separation (DMS) circuits. The role of the multi-density separation is discussed, and it is emphasized that for many processing problems -related to minerals and coals -it may be very important to perform two or more cuts at different densities in order to

The potential for dense medium separation of mineral fines using a laboratory Falcon Concentrator [PDF]

Minerals Engineering, 2017
Dense medium separation (DMS) is a technique used to separate particles based on specific gravity. Conventional DMS is, however, limited to coarse particle sizes and is not practical when processing fines.

Alternative Materials for Dense Medium Separations

International Journal of Coal Preparation and Utilization, 2009
In response to concerns regarding cost and future supply of magnetite, a study has been performed to evaluate the potential of alternative materials that can be used to generate a dense medium for coal-cleaning applications. Alternative materials included waste steel slag, fine sand, and high-density material existing in run-of-mine feed. Under certain
