Enhancing flotation selectivity via ultrasonic treatment on the froth: foam characteristics and underlying mechanisms

In flotation, improving selectivity is crucial to reduce concentrate ash content and achieve clean coal utilization; however, nonselective entrainment of fine gangue frequently degrades separation performance. This work innovatively applies ultrasound to the froth to investigate...

Study on internal flow field and flotation performance of a vortex-driven flotation cell for fine minerals

The efficient recovery of fine minerals remains a major challenge in mineral processing. Flotation is one of the primary methods for fine particle separation, and from the perspective of flotation dynamics, turbulence intensification is essential. In this study, a novel vortex-dr...
