Abstract

Cette invention concerne un appareil pour collecter des particules minérales dans une suspension épaisse ou des queues, comprenant une zone ou un réservoir de collecte comportant une ou plusieurs surfaces de collecte conçues pour être en contact avec un mélange d'eau et d'un matériau intéressant, le matériau intéressant contenant une pluralité de particules minérales d'intérêt ; et un matériau synthétique présent au moins sur la ou les surfaces de collecte, le matériau synthétique comportant une pluralité de molécules ayant un groupe fonctionnel siloxane conçu pour attirer les particules minérales d'intérêt sur les surfaces de collecte. La ou les zones de collecte comprennent une bande transporteuse qui traverse la zone ou le réservoir de collecte, traverse une zone ou un réservoir de libération, et retraverse la zone ou le réservoir de collecte. Le mélange comprend une suspension épaisse de pâte à papier comprenant un minerai broyé avec des particules minérales d'intérêt qui en font partie, comprenant des particules minérales d'intérêt d'environ 500 microns ou plus.
