State-of -the-art of the coal slurry treatment technology and its developing trend

Following an overview of the coal slurry treatment technologies available both at home and abroad and the slurry treatment technologies currently in common use, the author goes to elaborate on the efficiencies of such technologies as addition of filter aid, application of external electrical field, magnetic field sedimentation and ion adsorption, by way of example. Finally, a brief analysis is made about the developing trend of coal slurry treatment technologies, which may serve as a reference for future research workers.
