  • Why is the froth flotation method only used for sulphide

    This method is based on the principle of the difference in the wetting properties of the ore and the gangue particles with the water and oil. This method is used for that metals whose ore gets preferably wetted by the oil and the gangue by the wat...

  • Why Only Sulphide Ore Is Concentrated By Froth Flotation

    Such a separating process is froth flotation, and in the case of iron and other sulphide containing ores, it is usual to float the value metals off and depress the bulk of the iron sulphidesAbout 48% of the total pyrrhotite in the ore was reported in the copper-nickel concentrate, and only 52% in the tailing.

  • Which type of ore is concentrated by froth floatation process?

    Sulphide ores are concentrated by froth- flotation process. Only sulphide ores are concentrated by this method because pine oil selectively wets the sulphide ore and hence brings it to the froth.

  • Sulphide ores of metals are usually concentrated by froth

    The ore which can be attracted by the magnetic field can be concentrated by the process of magnetic separation. Among the ores mentioned in table 6.1, the ores of iron such as haematite (Fe 2 O 3), magnetite (Fe 3 O 4), siderite (FeCO 3), and iron pyrites (FeS 2) can be separated by the process of magnetic separation.

  • Froth Flotation Process Detailed Explanation With

    Basic Principle of Froth Flotation Process. The process of froth floatation starts with the Comminution process in which the surface area of the ore is increased. First of all, the ores are crushed into very fine powder sized particles and mixed with water. The mixture obtained is called Slurry.

    In some sulphide ores of copper, zinc and lead, the concentration is brought by 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 non-wettability of the mineral

This mixture is taken in a flotation tank.

  • Explain the froth floatation process? askIITians

    This process is called concentration of ore. This process is mainly used for sulphide ores. The principle of froth flotation process is that sulphide ores are preferentially wetted by the pine oil, whereas the gangue particles are wetted by the water. In this process, a suspension of a powdered ore is made with water.
