Effect of ultrasonic treatment on flotation of calcite, barite

2013-7-18  The effects of ultrasonic waves on the flotation of calcite, barite and quartz have been investigated in the case of single and mixed minerals. In the case of single minerals, ultrasonic treatment has a positive effect in the flotation performance of calcite and barite, while showing a negative effect in the case of quartz.
