Coal Cleaning. Coal cleaning is an option for removing mercury from the coal prior to utilization. Of the more than 1 billion short tons of coal mined each year in the United States, about 600 to 650 million short tons are processed to some degree [91 ]. Coal cleaning removes pyritic sulfur and ash. Mercury tends to have a strong inorganic ...Web
