Coal Mining Effluent Guidelines | Effluent Guidelines | US EPA

Coal preparation plants remove waste material from coal by washing and concentrating. The plants may also sort and screen coal by size, and may crush the coal to facilitate handling and processing. The coal may be stored at several stages in the process of preparation and transport to the final customer. This paper describes the technique developed by the Australian Coal Industry Research Laboratories (ACIRL) for the treatment of bore core samples to obtain data for coal preparation studies of the target reserves. The particle size distribution within the sample has a significant influence on the relationship between the yield and ash per cent of the...

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. Coal preparation moves volumes of solids that abrade and erode equipment. Over the equipment lifetime, ongoing maintenance and replacement can result in extra expense and increased downtime. Wear resistant linings from Saint-Gobain provide unmatched abrasion and corrosion resistance and last many times longer than carbon steel.

THE CHALLENGE OF COAL PREPARATION

Conventional coal preparation plants account for about 25% of the cost of the total surface facility. The coal preparation plant cost may comprise 5-15% of the cost of a coal mine. A thermal dryer installation may cost 25-30% of the cost of a coal preparation plant. The cost of coal cleaning itself may be 15-25% of the cost of mining the coal. Ultrafine Coal Cleaning Recent studies have found that spirals such as the SX7 can provide an effective gravity-based separation performance for -100 mesh coal. Required volumetric flow rate is around 15 gpm/start and feed solids content should be nearly 15% by weight. Currently, two U.S. coal preparation plants use spirals in this application.
