Standard Test Method for Determining the Washability

5.2 The usefulness of this test procedure and the usefulness of the results derived from washability testing are directly related to the care exercised in developing and following the sampling regime while taking into consideration the desired degree of precision. For more exacting work, it will be necessary to know the general washability characteristics of the material in question.

Washability tests of Illinois coals: Electronic Edition

Test Procedure and Washability Analyses The coal from this mine was screened into the sizes given in Table 23. All sizes are exact screen sizes except the 5 x 3-in. coal. This is the coal that remained on a 3-in. round hole screen after being passed through a single roll crusher set at approximately 5 inches.

Washability an overview ScienceDirect Topics

The behavior of coal in density-based cleaning processes can be predicted from a series of float-sink (or washability) tests carried out on a crushed sample in the laboratory.The sample is placed in a heavy liquid of known density (e.g., 1.40 g cm − 3) and the floating fraction skimmed off for weighing and analysis.The sinking fraction is then placed in a liquid of somewhat higher density
