  • Effect Of Pulp Density In Froth Flotation

    It is possible in froth flotation to realize that the particle size distribution influences both the physics of a process by controlling the collision mechanism between particles and bubbles and the degree of liberation (Machado Leite 1992). pulp density in froth flotation process for copper

    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.
