Abstract
A column flotation system including tailings recirculation. The system includes a column for particle separation and a gas injected reactor providing the site for bubble generation within a treated slurry feed. The reactor may contain a plurality of the spaced internal discs that cause shearing of the slurry to generate and entrain bubbles therein. The column may contain internal partitions in order to accommodate additional reactors. Recirculation of the tailings permits increased bubble control and improved particle separation.
