  • 's flotation REFLUX™ revolution International

    In a normal flotation cell as you increase the gas flux, you start entering an operating condition where you lose the interface so there is no discernible difference between the pulp and the froth – so called flooded conditions. For example if you run a conventional cell at the same gas fractions as we run the RFC, you start operating at flooded conditions which results in bubbles and pulp
