The Effect of Power Ultrasound in the Production of

Power ultrasound may be applied to enhancing the processing of minerals. The enhanced performance is achieved through the very localised high-energy release at the mineral surface from the collapse of cavitation bubbles produced by power ultrasound. This gives rise to two effects: initially, the rapid cleaning of mineral surfaces of oxidation products and coatings...
