Abstract
Disclosed herein are methods of sorting coal into multiple fractions based upon x-ray absorption and size characteristics in order to remove rocks and other contaminants of various sizes from coal. The use of such dry processing of coal is desirable as it reduces pollution and transportation costs. The multi-fractional sorting of coal is a more efficient manner for identifying and removing rock and contaminants from coal.
