For the beneficiation of coarse coal (larger than 56 mm), there are basically two wet routes: with dense medium based technologies, or with wateronly technologies. Flotation and agglomeration principles will not work since the particles are too large and will sink, irrespective of the quality (save maybe the very lightest of density fractions).
