  • Flotation columns: Getting the most from fine ores - Outotec

    In direct flotation, this froth corresponds to the concentrate. Hydrophilic particles flow down and leave the column through a barometric leg, which includes a level control system. This corresponds to the underflow and, in the case of direct flotation, to the tailings. Figure 2 illustrates the flotation process within a column. Figure 2.
