Cyclone separators or simply cyclones are separation devices (dry scrubbers) that use the principle of inertia to remove particulate matter from flue gases. Cyclone separators is one of many air pollution control devices known as precleaners since they generally remove larger pieces of particulate matter. This prevents finer filtration methods from having to deal with …

High density media separation: The pretreated ore slurry is fed to a DMS cyclone or bath where separation takes place. A thick medium is introduced and the mixture is stirred to ensure even distribution. Mineral separation: As the ore slurry enters the DMS cyclone or DMS bath, the minerals are denser than the media and settle to the bottom.
