2020.2.10 The deslime screens make the next cut and most prep plants size to minus 1 mm. The media, or magnetite, is recovered by drain-and-rinse (DNR) screens, which are placed on both the clean coal and refuse streams. Magnetite is quite expensive right now and losing it to either stream is a major concern for heavy-media plant operators.

The dense medium cyclone – past, present and future
2018.1.15 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.

Investigations of the effectiveness of lead disposal from
the removal of lead from coal by its cleaning is possible due to lead association with coal mineral matter, mainly in sulphide form. Studies [40-41] on the removal of heavy metals, (including lead) from coal by the coal cleaning process in a dense medium on a laboratory scale were carried out. These studies confirmed lead affinity to coal mineral
