"LOW-RANK COAL: Its Present and Future Role in the United ...

Low-rank coals-lignite and subbituminous coal-are those that have been subjected to the least metamorphic change during the coal-forming process. As such, they retain greater fractions of moisture and volatile matter and contain less fixed carbon than the high-rank coals-bituminous and anthracite. The primary measure used to classify the lower ranks of coal is the heating value.
