  • Write a short note on froth floatation process. - JEE

    Froth floatation process is used for the concentration of sulphide ores mainly. The particles based on differences in the ability of air bubbles that selectively attach to specific mineral surfaces in mineral water slurry are separated by this method. In this method, crushed ore is suspended in water and air is passed through suspension

  • CHAPTER-9 FROTH FLOTATION AND ITS APPLICATION

    The flotation method of concentration, used extensively for other metal ores, has only recently been utilized for hematite iron ores. It can be applied as either the sole concentration process or as a final concentration stage to ensure a high-grade product. In the flotation process, air is bubbled through a suspension of fine iron ore in water

    Mar 28, 2016 The froths produced in pulp-body-concentration processes are small-bubble, coherent and persistent, and characteristic. The volume of gas effectively utilized in floating the mineral is. of the order of 20 to 50 cu. ft. per cu. ft. of solid floated. 1 The general rules follow: 2 The variables affecting froth flotation

  • Extraction of Zinc: Froth Floatation Process, Roasting

    Jan 17, 2022 The principal ore of zinc used for its extraction is Zinc blend ( Z n S). As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200 K to obtain zinc oxide ( Z n O). It is then reduced to Z n by coke at a temperature of 1673 K

    1.2.2.1.2.2.1 Froth Flotation. The froth flotation process is more than a century old and was developed over a long period of time [8]. It takes advantage of the surface chemistry of fine particles—if one particle’s surface is hydrophobic and another is hydrophilic, upon generation of air bubbles, the hydrophobic particles tend to attach to

  • What is the role of adsorption in the froth flotation

    Hint: We know that the froth flotation process is used to concentrate the sulphide ores. Collectors and stabilizers are used in the process of froth floatation. Froth floatation process is based on the principle of difference in the wetting properties of ore and gangue with water and oil

  • Choose the correct statement(s) for froth flotation

    In some sulphide ores of copper, zinc and lead, the concentration is brought by the froth flotation process.In this method, the advantage is taken of the preferential wetting of the ore by an oil. The finely ground ore is taken in a tank containing water and 1% of pine oil or turpentine oil. Collectors (e.g., pine oils, fatty acids, xanthates, etc.) enhance the non-wettability of the

  • CHAPTER-9 FROTH FLOTATION AND ITS

    A. Vidyadhar and R. Singh INTRODUCTION Froth flotation is a process used to separate minerals, suspended in liquids, by attaching them to gas bubbles to provide selective levitation of the solid particles. It is most extensively used process for the separation of chemically similar minerals, and to concentrate ores for economical smelting
