34% ash level in coal produced using ROM coal with 40% ash, gives the most appropriate solution. For the low performing power plants (where the poor quality of coal has been identified as the reason for low performance), any increase in the PLF with the use of washed coal will result in higher breakeven cost of washed coal.

Coal analysis
Coal is usually washed by passing it over a bath of liquid of known density. This removes high-ash value particle and increases the saleability of the coal as well as its energy content per unit volume. Thus, coals must be subjected to a float-sink test in the laboratory, which will determine the optimum particle size for washing, the density of the wash liquid required to remove the maximum

Washability
To determine the partition curve for a cleaning operation, one needs the yield of clean coal from this operation and the results of float–sink tests for both products—that is, for the clean coal and the refuse. Such data allow the reconstituted feed to be calculated, and from this can be found the partition coefficients, which give the percentage of each density fraction reporting to

COAL CHARACTERISTICS
coal is heated to 950°C (1,742°F) in the absence of air under specified conditions
An overview of analytical methods used to determine inorganics in coal is given by Huggins (2002), and mineral matter in coal is presented in Chapter 2 of this book. A common method for determining whether a mineral or element will partition during beneficiation is through analysis of the float/sink fractions for different size fractions (Querol et al., 2001). As stated in Huggins (2002

This value is important for determining how the coal is washed (cleaned, or beneficiated) to remove mineral impurities that lower the coal''s heating value. So the conversion factor a specific mine or coal company might use to estimate the tonnage of a particular seam may differ from 1,800 tons/acre-foot, depending on the coal and reason for the calculation.
