报告摘要：
Froth flotation is a physiochemical process widely used to separate materials based on differences in surface wettability. This presentation describes a method to improve the performance of froth flotation and mitigate the issue of over-frothing commonly encountered in industrial flotation operations. Lab-scale and pilot-scale tests were carried out for various coal and mineral particles in flotation machines of different type in the presence of acoustic sound at a frequency below 500 Hz and the results were compared with those without sound. It was found that use of the acoustic sound led to significantly increased flotation efficiency, at modest additional energy cost and reduced reagent consumption, mitigating the overfrothing issue if any. The mechanisms of enhancement of flotation by low-frequency acoustic sound were discussed with respect to bubble-bubble and bubble-particle interactions studied through measuring the stability of thin liquid films.
