flotation cell control

flotation cell control

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

    Modelling for froth flotation control: A review

    Mar 01, 2021 The dynamic of the flotation froths has a strong influence on the overall performance of flotation cells, and thus, its control is difficult to achieve (Neethling and Brito-Parada, 2018). In addition to those controllers based on froth images (such as those mentioned in the introduction), only a few researchers have addressed the integration of

    Flotation stabilization and optimization

    flotation cells are connected in a network and the tailings stream from one cell is likely to be fed to another cell. Similarly, the concentrate flows will generally be fed into banks higher up in the circuit. This results in strong interactions between levels in a flotation circuit. Thus if a change in control action is made at any point in
