<p>An inclined screen separator 12, 14 is used to separate adsorbent particles from a slurry, which is being treated in vessel 1 by countercurrent contact with the adsorbent particles, so that the separated particles may be conveyed from one chamber 3 to the next chamber 4. The chambers are separated by a sieve 5 which allows the slurry to pass through but not the adsorbent. The slurry may be finely divided ore containing Cu, Au or U which is picked up by the adsorbent, the adsorbent loaded with the metal being discharged at 22 and depleted ore at 8. The separator comprises a level detector 23 which acts in conjunction with a timer 20 to control the flow of adsorbent-slurry mixture up line 11 and/or the return of separated slurry and adsorbent through lines 17 and 19, intermittently or continuously. <IMAGE></p> |
