Dense medium separation using a teetered bed separator

Minerals Engineering, 1999
Abstract A Teetered Bed Separator (TBS) was used autogenously, and with a range of media, to study the dense medium separation of a coal feed slurry, −2.00+0.375 mm in size. The feed slurry consisted of separate portions of a clean coal fraction, and a mineral matter fraction. A series of experiments were conducted using (i) the clean coal only, (ii)

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

Characterisation of Ferrosilicon Dense Medium Separation Material

Hyperfine Interactions, 2003
Ferrosilicon is used in the dense medium separation of iron ore at Kumba resources, Sishen, South Africa. Due to high cost and losses that occur during use, maximum recovery by means of magnetic separation is aimed for. The purpose of this project was to determine the characteristics of the unused Fe-Si and then to characterise the changes that occur ...

Static and Dynamic Stability in Dense Medium Separation Processes

Mineral Processing and Extractive Metallurgy Review, 2000
Static and dynamic stability in dense medium separation processes are defined, and a model for dynamic DMS systems provides the density differential (a measure of dynamic stability) as a function of the static stability and parameters related to the geometry of separatory vessels and operating conditions.

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

Appraisal and Optimisation of Dense Medium Plant Separations

Coal Preparation, 1992
An extensive plant-orientated testwork campaign was undertaken to quantify and determine the causes of significant dense medium cyclone operating inefficiencies. Comprehensive plant trials, with 20–30 people sampling up to 100 process (medium and coal) streams simultaneously for eight hour shifts permitted both magnetite media and coal processing ...

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 ...
