    Froth Flotation - Metallurgist & Mineral Processing

    Froth flotation is one of the most versatile and flexible of all mineral separation processes. Reasonable results are fairly easy to obtain but outstanding performance from a circuit requires constant attention and good understanding of the process and ore. Some of the variables that affect the operation and control of a flotation process are

    Froth Flotation. Froth flotation for separating discrete mineral particles from gangue was developed in the early 1900s and depends upon differences in the surface chemistry of the mineral species involved. At Hazen, our knowledge and experience in this field include the commonplace and the exotic. We have studied not only the flotation of sulfides, gold ores, iron

    Apr 25, 2021 Froth flotation utilises the differences in physico-chemical surface properties of the particles to be separated, especially differences in hydrophobicity. Bubbles rise through a heterogeneous solid-liquid suspension, accumulating certain of the solid particles, which attach by virtue of their hydrophobicity
