  • Talk:Froth flotation - Wikipedia

    I think "flotation" should remain a separate keyword and not integrated into "froth flotation". In the paper industry, flotation is the key process in the recycling process for recovered paper, the deinking process. Nobody uses the term "froth flotation". I might find the time to suggest updates for both the keywords flotation and deinking.

  • Flotation Reagents - Mineral Processing & Metallurgy

    Flotation Frothers What is the Function of Frothers. The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.
