    Flotation is also used to remove impurities before hydrometallurgical treatment (ie, carbon pre-flotation) to purify low-sulfide and refractory ores for further processing. Flotation is considered to be the most cost-effective method of concentrating refined gold and is often used in conjunction with flotation

  • Mineral Processing Froth Flotation

    Froth Flotation is a mineral processing process achieving solid-solid separation by taking profit of the chemical attribute leading to the possibility of selectively controlling the relative surface hydrophobicities of the various components mixed in an aqueous medium. Froth flotation is the most common industrial process based on this approach. The term surface hydrophobicity refers to the ...

  • 1 Froth Flotation – Fundamental Principles

    1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and removed, while the particles that remain completely wetted stay ...

    In flotation mineral processing, the flotation machine scrapes the foams with minerals, to separate the valuable minerals and gangue minerals. In this period, the foam pulp contains solid, liquid and gas materials. The process by which the mineral particles in the pulp adhere to the bubbles is called bubble mineralization. The process of bubble mineralization has certain selectivity to ore ...

  • TECHNICAL NOTES 9 FLOTATION - Mineral Tech

    FLOTATION Flotation is the most widely used mineral separation method. It is the preferred method of mineral recovery for many of the most important minerals that are recovered and large tonnages of ore are processed by flotation annually. The underlying principles of the flotation process are well established but it has proved to be unusually difficult to build quantitative predictive models ...

    The use of flotation for recovery of fine coal is also widely practiced. The flotation process begins with a modification of the surface properties of the desired mineral. The addition of surfactants renders the mineral surface hydrophobic (water-hating), so that the mineral may preferentially adhere to air bubbles and float to the surface. The ...
