In a method and apparatus for separating low density particles from feed slurries, a bubbly mixture is formed in a downcomer (14) and issues into a mid region (12) in a chamber (1). An inverted reflux classifier is formed by parallel inclined plates (6) below the mid region allowing for efficient separation of low density particles which rise up to form a densely packed foam (16) in the top of the chamber, and denser particles which fall downwardly to an outlet (29). |
