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