NGM is said to affect the separation performance of coal cleaning equipment and is believed to be the primary reason or at least an important reason for misplacement between the products ...
Coal washing. Coal washing involves grinding the coal into smaller pieces and passing it through a process called gravity separation. One technique involves feeding the coal into barrels containing a fluid that has a density which causes the coal to float, while unwanted material sinks and is removed from the fuel mix. ...
Coal-washing wastewater is the residual produced by the coal industry, which may represent a high risk of serious environmental problems worldwide. However, prevailing coal-washing treatment processes are hardly ideal for achieving the goal of solid–liquid separation due to the wastewater's extremely stable physicochemical …
Emissions Control Strategies for Power Plants. Bruce G. Miller, in Clean Coal Engineering Technology, 2011 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].
