flotation cell control

Flotation cells require precise control of compressed air because the frothing process efficiency is based on the speed of the froth as it moves from the surface of the slurry to the recovery area. The speed of the froth is controlled by the air bubbles induced into the flotation cell, tank level and reagent dosages

    a review of frothflotation control- sciencedirect

    Sep 14, 2011 · Stenlund and Medvedev, 2000, Kämpjärvi and Jämsä-Jounela, 2003, Carr et al., 2009 report that flotation cells traditionally use feedback PI control to ensure pulp levels remain at desired set-points; although Wills and Napier-Munn (2006) add that feedforward control is also regularly integrated to account for flowrate variations upstream. This is achieved by manipulating the tailings flow from the …

    SlurryFlo control valves have successfully provided flotation technology solutions in mechanical flotation cells and column flotation cells. Each flotation system has unique challenges and requirements that are well suited to SlurryFlo’s control valve technology. Our goals are to improve tailings flow control and reduce valve wear rates. The following are three (3) key benefits that SlurryFlo offers the flotation …

    modelling for frothflotation 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 froth performance into control strategies

    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 consideration as the goal …
