Washability - an overview | ScienceDirect Topics

The results of washability data are indicated in Fig. 10.5. It gives the sulphur content of that raw coal size for each density fraction. The fractional sulphur content is at a peak at 1.5 relative density (RD). It can be also seen from the same figure that the cumulative sulphur content is reduced to some extent at cut-off points below 1.3 RD.
