Eriez developed the HydroFloat Separator specifically to treat coarse material. 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.
The HydroFloat Separator was invented to provide a solution for industry to overcome a long-standing challenge - the efficient recovery of particles coarser than 150-200 micron.
Conventional and column flotation cells are well suited for concentrating ores ranging from 50-150 micron. However, their effectiveness when treating particles coarser than this threshold is suspect due to turbulence and buoyancy issues.
Process engineers no longer have to try to achieve optimum performance in a single unit operation. Coarse material can now be isolated and treated in a separator specifically designed for and ideally suited to selectively recover coarse particles that are otherwise lost using conventional methods..
