  • FROTH FLOTATION PROCESS AND FROTH STABILITY
    Publication number: 20230129507
    Abstract: A method for stabilising a froth or a foam comprising subjecting the froth or foam to vibrations or sound waves having a frequency of less than 20 kHz. The frequency may be less than 1 kHz, for example, a frequency of from 300 Hz to 500 Hz, or from 300 to 450 Hz, or from 300 to 400 Hz. A method for froth flotation is also described.
    Type: Application

  • A SENSOR FOR MONITORING FLOTATION RECOVERY
    Publication number: 20230014341
    Abstract: An apparatus (20) for monitoring flotation performance apparatus comprises an arm (21) having a paddle (22) attached at one end. The apparatus (20) forms a sensor to monitor real-time flotation performance by measuring the drag exerted by the overflowing froth onto a cantilever beam arm. The strain exerted on the beam or arm can be directly correlated to the efficiency of the froth flotation process.
