Washability - an overview | ScienceDirect Topics
From the float and sink data of the two size fractions, 75–25 mm and 25–0.5 mm of a raw coal sample, washability curves are drawn as in Fig. 7.21.From the curves, the results are read and recorded in Table 7.7 where it was found that the yield of clean coal was maximum when the specific gravity cuts of the two fractions are same, and also the direct ash of both is the same.
