The Direct Flotation Reactor (DFR) is a flotation cell that works on the principle of preventing the formation of a froth and froth slurry interface. Independent bubbles are removed from the collection zone in a gas phase/slurry phase. The flotation cell has a particle collection regime in the lower half of the vessel and the loaded bubbles are ...

The full-scale REFLUX™ Flotation Cell, which is shown in Fig. 3, had an internal diameter of about 2 m. The upper vertical section had a height of about 1.6 m and the inclined channels were nominally 1.0 m long, with a 20 mm spacing and an inclination of 70° to the horizontal. As discussed, the feed slurry entered through an air sparger ...

Unfortunately, the conventional flotation cell achieves high recovery only in limited size ranges. For example, a sulfide ore might float very well at 90 to 120 microns, but not at 50 or 150 microns. The research to date has identified two main reasons for the upper limit on floatable particle sizes.
