Appendix E: Coal Mining and Processing Methods Coal

Density separation. Raw coal consists of organic and mineral matter components, with specific gravities ranging from 1.30 for the lighter organic material to 2.5 for rock. Coal is cleaned by separating the lower-density organic material from the higher-density refuse.
