Preparation and Characterization of Super Pure Coal

Industrial washing oil as solvent, super pure coal was extracted and prepared from raw coal using heat extraction technology. The structures of raw coal and super pure coal were characterized by thermogravimetry and Fu Liye infrared spectrum. The results showed that the heat extraction rate of super pure coal was decreased with the increasing of coalification degree.

THE CHALLENGE OF COAL PREPARATION

Coal preparation is the practice whereby raw coal is modified to a more preferred form to enable its utilization. The methods employed to achieve this preferred modification need to be cost-effective, while also being appropriate to the raw coal, the scale of production and the ultimate end user requirements.

Coal Preparation Plant Advancements Mining USA

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.
