  • Froth Flotation Machines - 911metallurgist

    Froth characteristics change after supercharging, i. e., normal flotation is characterized by a relatively coarse shallow froth, while a supercharged froth is deeper and consists of a fine dispersion of air continuously passing up to the froth column from the super-aerated pulp. This condition helps materially in the removal of mineral-bearing froth and lowers reagent consumption. The reaction ...
