  • RFC-Upscaling New Reflux Flotation Cell Technology

    The key technology for the valuable-gangue particle separation in the process chain is flotation. In large tanks that are mostly operated in series air bubbles rise from the bottom to the top. If the chemical milieu is appropriate hydrophobic particles (e.g. copper sulfide) attach to these rising air bubbles and form a froth layer at the top

    Decades of research have shown that the basic mechanisms of particle collection in the pulp and froth zones of a flotation machine are different based on size and liberation of the ore particles. As a result using large vessels as roughers is a compromise since some ore particle types are recovered more efficiently at the expense of other types.
