meaning of reverse cationic flotation

  • Froth Flotation of Iron Ores - sapub

    Reverse cationic flotation is currently the most widely used flotation route in the world. However, the iron metal loss in the de-sliming stage, which is an essential step in reverse cationic flotation, and the high reagent cost of amine collector are the common problems of reverse cationic flotation.
