Raw coal can't be ground without losing water from the sample, and inherent moisture can't be expelled in the standard manner without grinding. However, historically, raw coal has often been heated, either leaving some inherent moisture, but usually, by using high temperature, losing a lot of volatile combustible matter.

Coal is classified according to its heating value and according to the percentage of carbon it contains. For example, anthracite contains the highest proportion of pure carbon (about 86 to 98 percent) and has the highest heat value (13,500 to 15,600 Btu/lb; British thermal units per pound) of all forms of coal.
