The beneficiation of fine coal by dense-medium cyclone

made to the dense-medium process for the cleaning of minus 0 5 mm coal but the process had first to be refined to suit the circumstances. Pilot Plant With this objective the Fuel Research Institute in 1976 erected a dense-medium cyclone pilot plant for the beneficiation of minus 0 5 mm coal and commissioned it during the first quarter of 1977.
