Flotation cells design are residence time froth carrying area and lip length

Dec 10, 2021

Oct 13, 2009 If the residence time is met with a certain cell selection but the froth carry rate or froth lip loading are exceeded, what are the options? One option would be to increase the number of flotation cells to increase the froth surface area or concentrate lip length

    Aug 29, 2018 In flotation, the selection of the size, number and type of cell for a particular duty depends on two important factors. Firstly, the required flotation residence time and secondly, the physical constraints of how much concentrate can be recovered for a given froth surface area and concentrate lip length

    The froth mean residence time depends on the froth depth, gas flowrate, gas hold-up, and flow regime.In this work, the froth mean residence times were

    Traditionally, selection has been based on residence time scaleup from batch and/or pilot testing.-However reviewing other factors such as froth carry rate and lip loading is now considered to be equally as critical to ensure optimum performance. This paper reviews selection methodology used for modern flotation tanks, the

    Jul 01, 1998 This ratio, termed the froth residence time, has been proposed by certain flotation cell manufacturers as an effective method of accounting for the effect of the froth phase during flotation cell scale-up. However, at deep froth depths, or large values of froth residence time, the correlation between the data obtained from the 250 litre cell

    Once the froth is out of the flotation cell, it should break down rapidly to allow pumping of the concentrate. The mineral-laden froth is also referred to as concentrate or in coal flotation “the float product”. 1.1.3 Flotation Machines Froth flotation is performed in machines specifically designed for

    Particles enter the froth phase when a bubble carrying the particles crosses the pulp-froth interface. The froth phase floats on top of the pulp phase and is formed by the bubbles that break through the surface of the pulp phase. The water in the flotation cell is conditioned to promote the formation of a more or less stable froth

    Cleaner banks are focused on product grade and thus provide low residence time. As such, the number of cells are lower and the cells smaller. Column flotation is sometimes used as cleaners. Recycle streams are important to maximize selectivity and thus efficiency. [145-5-38]

    FCR measures the mass of concentrate (dry) that is removed from the flotation cell, per given area of froth per time (see Equation (4)). Lip length (LL) measures the amount of dry concentrate

    A number of radial launders can be installed, depending on the cell size, and can also be retrofitted to existing installations to increase concentrate lip length. Conclusion The selection of flotation cells can depend on residence time, froth carry rate and concentrate lip loading

    Jul_07 flotation cells design are residence time froth carrying area and lip length. Jameson Cells are contact dependent, not residence time dependent. In the Tank Froth Zone the grade of the concentrate is controlled by froth drainage and froth washing. Cells are designed to ensure an efficient, quiescent zone that maximises froth recovery

    Nov 01, 2009 A combination of laboratory-scale test work and design scale-up factors will determine residence time. However, the froth carry rate (dry tonnes of concentrate per square metre of froth surface area per hour, t/m 2 /hr) and froth lip loading (dry tonnes of concentrate per metre of froth lip per hour, t/m/hr) cannot be determined in a laboratory. This is because the froth is scraped during a

    Froth flotation is a good example of an engineering “system”, in that the various important parameters are highly inter-related, as shown in Figure 1. It is therefore important to take all of Chemistry Components Collectors Frothers Activators Depressants pH Equipment Components Cell Design Agitation Air Flow Cell Bank Configuration
