Abstract
This Bureau of Mines report describes the preparation characteristics of 10 coal samples collected from the significant coal-producing mines of Lucas, Mahaska, Marion, Monroe, and Wapello Counties in Iowa, with emphasis on physical desulfurization. All 10 samples were of high sulfur content as received ranging from 4.2 To 10.4 percent; the organic sulfur content ranged from 0.8 to 3.8 percent. The pyritic sulfur content of the samples could be appreciably reduced by crushing and washing and provided pyrite sulfur reductions ranging from 36 to 75 percent. Crushing to 3/8- inch top size and removing the sink 1.60 Specific gravity material would provide float coal products containing 3.5 to 6.0 percent sulfur. However, these coals could be burned at utility plants utilizing so2 removal processes with efficiencies ranging from 70 to 88 percent and still be in compliance with the current federal so2 emission regulation for stationary sources.
