<p>The invention provides a method and apparatus for the separation of particles from a particulate suspension. Apparatus for the separation of particles from a particulate suspension comprises a rotating flotation drum (10) with a feed distribution chamber (13). Particulate suspension feed enters the chamber through delivery pipe (20). The feed passes through holes (21) into the particle collection chamber (22). Air is passed into the particulate suspension through porous inner wall (29) and a froth is generated. The froth and particulate suspension pass into froth cleaning chamber (32). The froth is washed by being sprayed from washwater distribution pipe (47). Froth is removed from the drum by froth scraper (49) through froth removal chute (50). Unfrothed particulate suspension passes through openings (40) into weir chamber (41) and is removed through launder (45).</p> |
