2014-7-1  1. Introduction. The dense medium cyclone (DMC), also known as the heavy medium cyclone, is the work horse of modern coal preparation to upgrade run-of-mine coal in the 0.5–50 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 significantly improve industrial
