Froth Flotation Principle and Process
The froth stabilisers in the froth floatation process should be present in sufficient quantity to last until the constituent bubbles pass out of the pulp and the mineral is retained. Frothers are surfactant reagents that aid in the formation of froth. For example, pine oil, camphor oil, and so on. ... Froth flotation diagram.
