  • Froth FlotationFundamental Principles Semantic

    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 removed while the particles that remain completely wetted stay in the liquid phase.
