[email protected]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 1020 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.
