1 Froth Flotation – Fundamental Principles

2009-8-27  1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and
