  • Coal Cleaning - an overview ScienceDirect Topics

    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.

  • Cleaning of fine and ultrafine coal - ScienceDirect

    01/01/2013  For metallurgical markets, treatment of the entire raw coal classifier cyclone overflow stream by a flotation process is the most common strategy, due to the elevated market value of the coal. There are many fine coal cleaning process alternatives as well as wide variations in the overall circuitry arrangement.

  • Coal Cleaning - an overview ScienceDirect Topics

    The process of cleaning coal is a wet one, using large quantities of water (i.e., thousands of gallons per minute). As a result, vast quantities of dirty (fine rock-laden) water are produced. Beneficiation processes require clean water. Consequently, dirty water is processed, solids removed, and clean water recycled for further use in the plant.
