Coal Processing
Using a dense medium cyclone, denser materials are separated from less dense coal at a specific cut density (a specific point of density, which separates the ore into a valuable and non-valuable fraction). The coal product then flows onto the float drain and rinse screen, used for media recovery and dewatering. This ensures maximum media ...

Medium consumption is a significant component of the cost of operating a dense medium plant. This study aimed to identify and quantify many of the factors contributing to overall consumption, through extensive surveys of four widely differing dense medium mineral separation plants, and associated laboratory experiments.
An analysis of medium losses in coal washing plants
The medium, being costly, plays a crucial role in determining the economics of any preparation operation. Dardis (1987) quotes figures of 20–40% of dense-medium plant operating cost being attributable to medium loss for plants engaged in mineral separations employing ferrosilicon as the medium. The figure is 10–20% in the case of magnetite.

What is a DMS Plant?
A DMS plant, or Dense Media Separation Plant, involves a process that uses the principle of gravity to separate materials with different densities. Dense Media Separation is an efficient initial process to separate diamonds from diamond bearing material, after which the material will be further processes for the final diamond recovery.
