Dec 12, 2016· COAL PREPARATION 3. What Is Coal Preparation? • Coal preparation is the removal of undesirable material (ash, Sulphur, moisture)from the Run-of-Mine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities.
The method used to reduce the gross sample to the analytical sample must maintain the Integrity and representativeness of the sample while meeting the particle size and weight requirements as specified by the particular analytical methods. The preparation of a gross sample for coal analysis requires several processing steps.
EPA promulgated the Coal Mining Effluent Guidelines and Standards (40 CFR Part 434) in 1975, and amended the regulation in 1976, 1977, 1979, 1982, 1985 and 2002.The regulation covers wastewater discharges from mine drainage, coal storage facilities, and coal preparation plants.
