A Sustainable Alternative to Froth Flotation

2017-9-27  • Froth Flotation is one of the industry’s standard ways of concentrating low grade, fine particle sized minerals. • This process is done by using water as a medium and manipulating the particles surface chemistries into being either hydrophobic or hydrophilic then using air bubbles to separate the hydrophobic particles.

Flotation Froth Image Analysis by Use of a Dynamic

2016-1-1  Froth image analysis has been well established as a means to infer the performance of froth flotation cells in real time. Apart from linking the appearance of the froth to the behavior of the flotation system, the dynamic behaviour of the froth is also an important determinant of the performance of the flotation cell, and ideally, this information should also be taken into consideration.
