CHAMPAIGN -- In
the past, in the process of mining, 20 percent of coal was lost as
dust. Now, a team of researchers at the
Illinois Geological Survey,
a division of the Illinois Department of Natural Resources, has
discovered a method to recover that dust. The result is a coal that
is freer of impurities, such as sulfur. The dust is also no longer a
waste product requiring disposal.
