Options for Washability Analysis of Coal

The Australian Coal industry needs to find an alternative to the heavy organic liquids used to produce its coal washability analyses. Indeed, the existing Australian Standard for the Float and Sink analysis of coal is likely to be phased out over the next five years, and thus the matter needs to be urgently addressed to allow time to establish a new approach, with a new standard.
