  • Are Conditioning Tanks making a comeback - Outotec

    This can be achieved in a conditioning tank with an automatic water addition valve in a feedback loop with a sensor installed on the tank (e.g. differential pressure sensor) or the tank discharge to measure pulp density. Another function conditioning tanks serve is acting as a buffer in front of the first flotation cell

  • Precise Air Flow Measurement Improves Flotation Cell ...

    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.

  • Flotation Conditioning - Mineral Processing Metallurgy

    Flotation Conditioning is often necessary as it is not sufficient merely to make the addition of the various reagents to the pulp and then to proceed with flotation. Intimate admixture is essential in order not only to bring about their even dissemination throughout the pulp but also to ensure that the millions of particles of varying nature shall each receive its proper degree of treatment ...

  • Calculate Flotation Cell Capacities Volume vs Retention Time

    Five minutes conditioning time and 15 minutes flotation time are desired. Adding 15% as a volume factor for aeration, the estimated flotation cell volume needed will be 290 cubic meters. If cells of 29,000 Liters volume are chosen, N will be 10. Similarly calculating for the 5-minute conditioning time at the same pulp density gives (see below).
