Ore sorting can run into capacity and efficiency issues if particles are below 30mm. In contrast, dense medium separators can sort particles down to 0.75mm in size. If you're working with finer particles, dense medium separation is the way to go. Higher tonnages can also be accommodated with dense medium separation.
Keywords: heavy medium cyclone, heavy liquid, simulation, iron ores, manganese, chromite Introduction Dense medium cyclones (DMCs) provide more precise separation than other gravity processing methods, especially when the amount of material float/sink within ±0.1 density range is above 10% (Burt, 1984;Wills and Napier-Munn, 2006).
Heavy Media Gravity Separation Heavy media gravity separation involves using a mixture of fine media material, such as magnetite (SG 5.1) or ferrosilicon (SG 6.8), suspended in a slurry of water, to produce a media slurry with a specific gravity that will allow low density material(s) to float, and other high density material(s) to sink.
