The use of electrostatic demulsification methods to separate fine particulates of differing surface characteristics is disclosed. In one example, particles of hydrophobic coal and hydrophilic kaolin clay, each of nominal 3.5 micron mass mean particle diameter, were separated from a variety of stable...http://www.google.fr/patents/US5147045?utm_source=gb-gplus-shareBrevet US5147045 - Particulate separations by electrostatic coalescence
