Eriez' HydroFloat Separator for coarse particle mineral concentration delivers 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.

RFQ Form
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 semiliberated particles.
HydroFloat Separators Improve Coarse Particle Recovery through:
16in Ø Laboratory HydroFloat - Maximum Feed Rate: 2.0 stph
6in Ø Laboratory HydroFloat - Acrylic
6in Ø Laboratory HydroFloat - Stainless Steel
