ABSTRACT:
The specification describes particle-charging, specie-separating and concentration-enhancing methods and apparatus which operate on a substantially continual basis. The particles of each specie in a mixture are charged by surface contact, separated in an electric field according to their respective polarities by motion in the direction of the field, and the particles of like net polarities are transported in substantially continuous streams, each of opposite net polarity, running near each other, in a direction or directions transverse to the electric field, the streams being in communication parallel to the electric field, so as to transfer particles of at least one of the species to the other of the respective streams by virtue of continued particle contact and field separation of charged particles as the respective streams progress transversely to the electric field. The two streams can run in the same direction (co-current) or in respectively opposite directions (counter-current). The electric field is established between electrodes spaced not more than about 10 mm apart.
