    LEVEL CONTROL STRATEGIES FOR FLOTATION CELLS

    Jan 01, 2002 One of most commonly controlled variables in a flotation cell is the slurry level. The level in the cell influences the concentration and yield of mineral and it is therefore important that the levels in the cells remain stable. Level control of flotation cells is a very complex task due to high interactions between the process variables

    Sep 14, 2011 Similarly, traditional base level flotation control was applied to single cells, although modern control strategies are now regularly applied to entire banks of cells (e.g. pulp level control). The two higher tiers of flotation control are advanced flotation control (AFC) and optimising flotation control (OFC)

    Mar 24, 2021 Flotation cells are mechanical equipment that bring the ore in contact with air, water, and chemical agents. Their main function is to separate the previously conditioned slurry into a concentrate and tailings. The level of these cells is controlled by dart valves, which in turn are operated by actuators.The calculation of the level control valve (Dart) in flotation cells requires high
