Coal is cleaned by separating the lower-density organic material from the higher-density refuse. In heavy-media separations, the specific gravity of the medium used for separation, usually a suspension of finely divided magnetite in water, is chosen to achieve a given degree of separation depending on the characteristics of the coal, the ...


Magnetic density separation (MDS) is a density-based sorting process realized utilizing a "magnetic fluid" constituted by a liquid (i.e., water) and magnetic particles (i.e., iron oxide particles of about 10–20 nm) suspended in the liquid (Bakker et al., 2009).Through a special magnetic field (Rem et al., 2013) an artificial gravity is produced, as a magnetic force.
