<p>The specification describes specie-separating and concentration-enhancing methods and apparatus which operate on a substantially continual basis. The constituents of a mixture are separated according to their respective influencability by motion in the direction of a separation influence and the species of like net influencability are transported in substantially continuous streams (18A, 18B), each of opposite net influencability running near each other, in a direction or directions transverse to the separation influence, the streams (18A, 18B) being in communication parallel to the separation influence so as to transfer at least one of the separable species from one stream to another stream by virtue of continued separation of influenceable species as the respective streams (18A, 18B) progress transversely to the separation influence. The two streams (18A, 18B) can run in the same direction (co-current) or in respectively opposite directions (countercurrent).</p> |
