Like middle and high rank coals, sink and float experiments show the washing possibilities of low rank coals. Before the design of a coal preparation plant, the washability of raw coal must be obtained. The raw coal is classified as "easy to clean" or "difficult to clean" based on the content of near-gravity materials at specific gravities.
