• Flotation Froth

    Since plastics are generally hydrophobic materials, froth flotation has successfully been used for the separation of plastic materials. 5,137 5 137 For example, two plastic materials which are buoyant in a specific liquid phase can be separated from one another by the addition of a wetting agent which selectively adsorbs to one of the plastics and not the other.

  • Frothers & Froth Flotation | ArrMaz

    During the flotation process, frothers help create the ideal hydrodynamic conditions (such as bubble size and gas holdup) required within the pulp in the flotation cell. They generate froth that is stable enough to hold collected minerals on top of the pulp, mobile enough for removal, and decays quickly to assist with downstream operations.
