Heavy Media Separation - an overview | ScienceDirect Topics

39.3.3 Heavy media separation. Heavy media separation dates back to several centuries. Initially, a fine magnetite was used as a heavy media. In 1936, a plant was designed employing organic liquid as a heavy media for treating anthracite coal containing ore. The heavy media process is usually used for treatment of coarse coal above 9.5 mm in

Heavy-media Cyclones for coal cleaning | FL

Like the heavy-media vessels, Heavy-media Cyclones also are designed to clean coal and minerals based on their density differences. Using finely ground magnetite and water as the media to create a buoyancy effect for gravimetric separation, the Heavy-media Cyclone forces the lighter solids to its centre, where the slurry transports them upward and through the vortex finder.
