    Some of these conclusions are: 1) The flotation column cell performes better than conventional flotation cells due to the column's deep water washed froth and countercurrent contact mechanism. 2) Increasing the air rate decreases the grades of the concentrate due to increased entrainment, while the recovery moves through an optimum.

  • Column flotation froths

    Abstract. A fundamental study on the behaviour of flotation column froths is presented. Three main aspects were considered: hydrodynamic, cleaning (rejection of hydraulically entrained particles) and selectivity (separation between particles of different hydrophobicity).Column froth hydrodynamics were studied in a two phase (gasliquid) system.
