Of Minerals Froth Floatation

Froth flotation, separation of minerals differing little in density but greatly in wettability by surfactants that stabilize a froth formed on the surface of an agitated suspension of the minerals in water. See flotation. This article was most recently revised and updated by Erik Gregersen, Senior Editor.

  • Frothflotation

    Froth flotation is a selective process for separating minerals from gangue by using surfactants and wetting agents. The selective separation of the minerals makes processing complex that is, mixed ores economically feasible. The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement. Phosphates and coal are also processed by

  • Advantages And Disadvantage Of Froth Flotation Method

    The froth flotation method is that the mineral selectively attaches to the air bubble by flotation reagent based on the physical and chemical properties of mineral surface. It is not difficult to see that the first two methods mainly rely on the nature of the ore itself, while the froth flotation method mainly relies on the added flotation reagents for separation based on the nature of the ore itself.

    Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

    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
