ABSTRACT:
A method for separating components of a mixture containing particles which can be electrically charged from particles which can be only negligibly charged is disclosed. The mixture is fed onto an electric undulating traveling wave contact panel which is energized to a charging potential using A. C. voltage. The voltage is then increased to a separation voltage to effect levitation and movement of the charged particles away from the uncharged particles. Separation is accomplished by cycling the voltage between the separation and charging voltages until the charged particles are moved off the panel and the uncharged particles remain on the surface of the panel. The separated particles can then be collected separately.
