Introduction. A coal dense medium separation (DMS) plant makes use of the principle of density separation to upgrade mined coal and produce metallurgical coal or power station coal. The objective of the DMS plant operation is to produce coal product within a minimum quality specification and maximum possible yield (England et al., 2002).

The dense medium separation process (DMS) is a mature technology, and is widely used in mineral and coal processing. The dense medium cyclone (DMC) is the most ubiquitous of the DMS vessels in use, and deservedly so. It is efficient (when run properly), can process both coarse and fine sizes, and has a relatively small footprint.

Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries, and the industrial growth of that era in turn supported the large-scale exploitation of coal deposits. Since the mid-20th century, coal …
