Coal Beneficiation Technology 01

6.1 Coal Beneficiation Technology Options

For the beneficiation of coarse coal (larger than 5-6 mm), there are basically two wet routes: with dense medium based technologies, or with water-only 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).
