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