    2002-5-1  The flotation process can be more effective in desulfurization of the coal when the majority of the sulfur content of the coal is pyritic sulfur. In addition, it was believed that the higher percent of pyritic sulfur in the total sulfur content of the coal prompted the production of lower sulfur content clean coal, and the column flotation method can produce a cleaner coal product than the conventional flotation.
