Designed 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: Coal, Iron Ore, Industrial Minerals, and Base Metals. Applications include: Coarse Recovery in Split-Feed Flotation Circuits, Tailings Scavenging, Flash Flotation in Grinding Circuits.
