  • Flotation Froth - an overview | ScienceDirect Topics

    Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.

  • 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.
