View the full presentation here. The first in fluidized-bed flotation with more than 70 units installed worldwide! Eriez, a world leader in separation technology, has designed the new HydroFloat® Separator for coarse particle mineral concentration delivering the capacity of a density separator while maintaining the selectivity of a flotation device. Using a novel aeration system to disperse fine bubbles into a fluidized-bed environment, the HydroFloat Separator significantly increases the selective recovery of coarse particles by applying flotation fundamentals to gravity separation. Can be applied to: Sulfides Base Metals Iron Ore Industrial Minerals Potash/Phosphate Coal Applications include: Coarse Gangue Rejection in Split-Feed Flotation Circuits Tailings Scavenging PRINCIPLES OF OPERATION The HydroFloat® Separator is an aerated fluidized-bed (or teeter-bed) separator. The synergistic effect of combining flotation with gravity concentration results in an outcome that cannot be achieved by either approach alone. Air bubbles are dispersed by the fluidization system, percolate through the hindered-setting zone and attach to the hydrophobic component altering its density and rendering it sufficiently buoyant to float and be recovered. The use of the dense phase, fluidized bed eliminates axial mixing, increases coarse particle residence time and improves the flotation rate through enhanced bubble-particle interactions. As a result, the rate of recovery is high for both fully-liberated and partially liberated particles. HydroFloat® Separators Improve Coarse Particle Recovery through: Increased bubble/particle collision rates Increased bubble/particle sliding time Increased residence time Decreased mixing Decreased turbulence and detachment Decreased buoyancy restrictions Mike Mankosa, Ph.D, and Eriez Executive Vice President of Global Technology, co-authored three technical papers at the 2016 International Mineral Processing Congress (IMPC) focusing on the various coarse particle flotation applications.

Applications: SCAVENGING The development of the HydroFloat was based on applying flotation fundamentals to teeter-bed separation. The presence of the fluidized bed increases collision rates beyond that which can be obtained in open flotation cells. As a result, the HydroFloat excels as a scavenging device.

With this new separator, process engineers can now maximize efficiency by designing split-feed flotation circuits where coarse material is treated separately from the fines.
