  • Intensification of fine apatite flotation with microbubble

    Nov 01, 2020  The flotation column, which is made of plexiglass, is 168 m in height and 008 m in diameter Since the objective of this work is to intensify the flotation of fine apatite particles, the scaleup task is not concerned and therefore this small column is investigated for convenienceOne of the key parameters in flotation is the particle size distribution of the feed and it has been 2 shown in several studies that the optimal size range for flotation is relatively narrow, approximately 20 – 150 µm (Gaudin et al, 1942; Jameson et al, 2007)The effect of particle size distribution on froth of top size to bottom size of approximately 5:1 the occasion to classify the feed, also allows the fine fraction to be treated separately with technology that is more suitable for fine particle flotation another difference between fluidized beds and mechanical cells is how the fluid and particles move within the unit the residence timeFlotation technology For coarse and Fine particle recovery

  • Coarse PartiCle Flotation

    of the ore to a size suitable for conventional flotation, the HydroFloat can treat particles at a relatively coarse size up to and exceeding 800 microns The HydroFloat is able to maximize recovery of the value in this coarse particle size range while simultaneously creating a throwaway coarse tailings streamThe high probability of particle–bubble contact, and subsequent short residence times (five to ten seconds in the downcomer, allows for a much more compact column design than conventional column flotation cells (see Figure 1) The fine nature of the bubbles (03 to 05 mm in diameter) gives them enhanced carrying capabilities for fine mineral particlesJameson cell WikipediaIn The Days of gravity concentration, the art of ore dressing developed on the cardinal principle of saving the values at as coarse a size as possible Flowsheets were designed which featured an alternation of crushing and concentrating operations Thus an ore might be crushed to ½ inch, jigged to yield a finished concentrate and a middling; the latter being recrushed to ¼ inch, jigged a Coarse and Fine Particle Flotation Recovery
