ABSTRACT:
An electrostatic separation apparatus for conductive particles and insulating particles with reduced separation time and improved separating capability, comprises a substantially flat-plate shaped bottom electrode (26) provided on lower side, a substantially flat-plate shaped mesh electrode (22) provided above the bottom electrode (26) as spaced a predetermined distance apart from the bottom electrode (26) and having a number of openings (24) to allow particles to pass therethrough, a direct current power supply connected to at least one of the mesh electrode (22) and the bottom electrode (24), and a voltage is applied across the bottom electrode (22) and the mesh electrode (24), thereby forming a separation zone (10) between the electrodes.
