Flotation Columns Flotation columns provide a means for improving the effectiveness of froth flotation (Eberts, 1986). A column essentially performs as if it were a multistage flotation circuit arranged vertically (Degner and Sabey, 1985), with slurry flowing downward while the air bubbles travel upward, producing a countercurrent flow.

Study of the Technology for Gold Recovery from Gravity-Flotation …
