This allows ash content to be reduced without the use of water, while specific contaminants such as sulphur can be accurately removed. Since the xray technology is capable of detecting atomic differences in the rock, the almost pure carbon in the coal is relatively easy to separate from the waste rock.
Coal ash can be beneficially used to replace materials removed from the earth, thus conserving natural resources. EPA encourages the beneficial use of coal ash in an appropriate and protective manner, because this practice can produce positive environmental, economic, and product benefits such as: reduced use of resources,

2 #0183;#32;Wyomingthe largest coalproducing state in the countryhas no coal preparation plants, largely because the subbituminous Powder River Basin coal is low in ash. However, PRB coal has a high level of inherent moisture (~30 percent), which has stimulated some interest in thermal dewatering of the coal to increase its heating value and reduce its transportation costs (see Box ).

#0183;#32;Coal Ash. Every large coal plant in our country produces about 240,000 tons of toxic ash and sludge per year. It is the second largest waste stream in the country, and it contains 44 tons of mercury, 4,601 tons of arsenic, 970 tons of beryllium, 496 tons of cadmium, 6,275 tons of chromium, 6,533 tons of nickel, and 1,305 tons of selenium.
Interestingly, and not well understood, ash content of coal decreases with coal rank. In general, higher ash content is found in lignites and lower ash content occurs in anthracites. How the mineral matter is removed from the coal with change in rank requires more study.
