Abstract
An apparatus and method are provided for separating electrically neutral solid materials having different dielectric, shape, density or dipole moment properties by passing a mixture of such materials through a nonuniform electric field generated between an electrically charged arcuate surface and a flat horizontal grounded surface having a receiving end, a discharge end and two lateral edges, said arcuate surface being spaced above said horizontal surface and extending from about said receiving end to about said discharge end and from one of said lateral edges to at least midway between said lateral edges; a means for introducing said solid materials into the electric field near said receiving end and conducting said material through the field to said discharge end; and recovering one type of material from said lateral edge adjacent said arcuate surface and another type of material from said discharge end of the horizontal surface.
