    A dynamic model of fluidized-bed flotation

    Jan 01, 2019 The concept of fluidized-bed flotation (FBF) (e.g. HydroFloat TM) was recently introduced to improve the recovery of coarse particles (425 to 1180 m). In spite of encouraging results from the first industrial applications dating back more than a decade, FBF still remains an emerging technology in the global mining industry

    Fluidised-bed flotation is a technology which was developed about 15 years ago to overcome this problem (Kohmuench et al, 2001). Fluidised-bed cells operate in the absence of turbulence. Particle-bubble aggregates are gently transported to the concentrate through the fluidised bed, allowing for much higher stability efficiency (Mankosa et

    Jul 18, 2013 A new process for coarse particle flotation is described in which a fluidized bed is created in the flotation cell. The flow conditions are very gentle and the high solids concentration leads to rapid rates of capture of the particles. Experimental results are presented. It is apparent that the maximum floatable size for coal and minerals can
