Meaning Of Reverse cationic Flotation

  • An overview of the beneficiation of iron ores via reverse

    Despite the recent success of the reverse anionic flotation of iron ores in the Anshan province in China, reverse cationic flotation remains the most popular flotation route used in the iron ore industry ().Comparing reverse anionic and cationic flotation is difficult because the processes are governed by the chemical, physical and metallurgical properties of the iron ores.

  • 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.
