Unfortunately, all electrostatic separation techniques (drum-type, belt-type, plate-type etc.) suffer from the requirement that the feed material must be completely dry (Higashiyama and Asano, 2007). Aside from the heavy mineral sand deposits, almost all other discovered rare earth deposits (aside from the ion-adsorbed clays in southern China) require some form of comminution prior to separation and these
