  • Principles of Froth Flotation | SpringerLink

    For successful exploitation of differences in surface properties most ore minerals must be ground finer than 48–65 mesh. A light mineral such as coal (density circa 1.4) can be floated at 10 mesh, provided the bubble system on which it is borne is developed as a quiet layer of froth. Random changes of direction, acceleration, and collision ...

  • Recovering Gold through the Froth Flotation Process

     · Froth flotation works by exploiting the hydrophobic properties of gold molecules. First, ore is ground into an extremely fine powder. The powdered ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold''s hydrophobicity. This mixture is placed into a large tank filled with distilled water.
