Desulfurization of Various Midwestern Coals by Flotation

• Description:
  Laboratory batch flotation tests were conducted to determine the viability of the Bureau of Mines coal-pyrite flotation process in desulfurizing various coals from the midwestern coalfields. Nine coals obtained from western Kentucky and Illinois were used in the study. In addition to the Bureau's coal-pyrite flotation process, some of the coals were subjected to two-stage rougher-cleaner coal flotation for comparison. The results of this work showed that up to a 70-percent pyritic sulfur reduction could be obtained by flotation and that the Bureau's coal-pyrite flotation was superior to rougher-cleaner coal flotation. Because many of the coals retained far too much sulfur even after second-stage flotation treatment, it was concluded that these midwestern coals are more difficult to desulfurize by flotation than are the Appalachian coals tested in earlier Bureau experiments.
