  • Electrostatic separation of particulate material
    Patent number: 5704490
    Abstract: Electrostatic separation is used to separate electrically conducting particles from electrical insulator particles by attracting the conducting particles to a separating electrode, whilst the insulator particles remain substantially attached to a carrier electrode.
