摘要：Separation of hydrophobic particles from a mixture of particles in a fluid isperformed by providing a fluidized bed as a relatively non-turbulent contacting

mechanism in a flotation cell incorporating a settling chamber located immediately above

the fluidized bed. Hydrophobic particles attach to bubbles in the fluidized bed and riseto the interface with the settling chamber where non-hydrophobic particles flow over thelip of an internal launder and are removed as tailings at. The hydrophobic particlesattached to bubbles float upwardly in the relatively placid settling chamber whereunwanted gangue can fall back to interface. The bubbles form a froth layer at the uppersurface of the settling chamber, and flow over the launder lip carrying the hydrophobicparticles. An operation of the apparatus is kept stable by recirculating fluid from thesettling chamber via pip and pump to mix with new feed entering at duct.
