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 nonfloatable 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.

Get PriceFroth flotation utilises differences in physicochemical surface properties of various minerals to achieve separation. Frothers are added to stabilise bubble formation in the pulp phase and to create a stable froth at the top of the cell. The significance of froth stability in mineral flotation has been reviewed recently (Farrokhpay, 2011).

Get Priceflotation reagents must be added to the pulp. Generally the most essential reagents in flotation process are the collectors, which are used to adsorb on mineral surfaces, rendering them hydrophobic and facilitating bubble attachment [5]. The frothers are used to maintain a reasonable stable froth during froth flotation.

Get PriceFroth flotation depends on differences in surface properties between coal and shale. Air bubbles are generated within an aqueous suspension of fine raw coal with a solids concentration of less than 10%. The hydrophobic coal particles attach to the air bubbles and are buoyed to the top of the froth flotation cell where they are removed as froth.
