Mineral Separation by Froth Flotation | Douglas W. Fuerstenau, Ronaldo
Froth flotation is the separation process whereby small mineral particles are captured by air bubbles and removed from the slurry as a froth. Consequently, two broad types of reagents are necessary in flotation: reagents to control the wettability of mineral particles and reagents to control foaming or frothing.
