  • 6.1 Coal Beneficiation Technology Options

    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

  • Beneficiation of Fine Coal Using the Air Table

    fine coal and lower separation efficiency contributed to their demise. Currently, China is the leader in using dry table and dry dense medium separation [11] processes. At present, in China about 130 million tonnes of coal is being processed using the dry cleaning techniques [12].
