The dense medium cyclone (DMC), also known as the heavy medium cyclone, is the work horse of modern coal preparation to upgrade runofmine coal in the –50 mm size range. Its working principle has been well documented (King and Juckes, 1984, Svarovsky, 1984, Wills, 1992, Chu et al., 2009a). A small improvement on the performance of DMC may ...

Tracing the Best Outcome for Dense Media Cyclones | Coal Age

For dense medium applications, conventional density tracers may be retrieved by hand (or by scoop), and the partition curve is defined in less than one hour. Lightweight magnet panels, installed in drainandrinse screen launders, proved effective for recovering ferromagnetic tracers as small as 2 mm, but the technology was not widely adopted.
