  • Flotation Froth an overview ScienceDirect Topics

    Joan S. Esterle, in Applied Coal Petrology, 2008 3.7.3 Froth Flotation/Column Flotation of Fine Particles. Froth flotation is a long established technique in mineral processing. Extensive discussion of flotation can be found in the book by Leja (1982); see also recent work by Fecko et al. (2005) and Melo and Laskowski (2006).

  • Froth zone modelling of an industrial flotation column

    May 01, 1998 May 01, 1998 In this paper an experimental study of the froth zone behaviour in an industrial flotation column, is presented. The column is rectangular, 2 8 m 2 in cross-section and 14m height, and is part of the second copper cleaner circuit of the Colon concentrator at El Teniente, Codelco-Chile. The column produces 30 tph of 32% copper concentrate.

  • Flotation Cell an overview ScienceDirect Topics

    As an alternative to agitated cells, bubble columns—used in chemical engineering practice as chemical reactors—were proposed for the treatment of fine particle systems. Flotation columns, as they came to be known, were “invented” back in the 1960s in Canada [35]. The main feature that differentiates the column from the mechanical ...

  • Flotation Machine an overview ScienceDirect Topics

    The flotation column patented in Canada in the early 1960s and marketed by the Column Flotation Company of Canada, Ltd., combines these ideas in the form of wash water supplied to the froth. The countercurrent wash water introduced at the top of a long column prevents the feed water and the slimes that it carries from entering an upper layer of ...

  • Simulation of Venturi Tube Design for Column Flotation

    flotation process. That matched the result from response surface method, the required energy increases as the diameter increases, after 215.96 mm. For an industry flotation column, multiple standard venturi tubes function better than one scale-up tube. Additionally, smaller tubes are easier to fabricate and replace. Multiple tubes may also

  • A study of bubble particle interactions in a column

    Since Boutin and Tremblay invented the flotation column in the early 1960s, a column flotation technique has rapidly developed (Zhang et al., 2013). This work aims to study the interaction between the particle and bubble in the flotation column.

  • Column Flotation Cells Mineral Processing amp Metallurgy

    Feb 28, 2016 Feb 28, 2016 Cleaner column flotation succeeded in producing final concentrate grades of 28 to 29 pct Cu and 1.37 oz Au/st with recoveries of 96.1 pct for Cu and 96.3 pct for Au. Effect of Aeration Rate. Flotation columns are generally operated at a maximum aeration rate for any given set of conditions in order to maximize flotation recovery and throughput.
