  • Column reverse rougher flotation of iron bearing fine

    Sep 01, 2020· In the column flotation collection zone, the rising bubbles capture the hydrophobic particles and the froth zone is enriched with the aid of washing water (Finch and Dobby, 1990).The drop back material from the froth (mostly middlings) returns to the collection zone, remaining at the pulp-froth interface and eventually exiting the column either by the concentrate or the tailings stream.
