Flotation intensification and monitoring

A versatile method to improve flotation efficiency using low-frequency acoustic sound . With using sound at a frequency below 500 Hz, significantly improved flotation efficiency was obtained for coal and metalliferous ore, especially in the coarse size fractions. This approach enables improvement of flotation efficiency at modest additional energy cost and reduced reagent consumption, mitigating the overfrothing issue if any. This technology has entered industrial demonstration stage.
