2013-1-1 · Spiral concentrators, water-only cyclones and fluidized-bed systems are capable of treating particle sizes as coarse as 3 mm. Compared to all the coal cleaning processes, dense medium cyclones provide the most efficient cleaning of fine coal (De Korte, 2002, Lundt and de Korte, 2010). However, the difficulty and cost associated with the overall circuit, including the magnetite recovery system, have limited the application in commercially operating fine coal
