 · Lignite raw / heavy : 900 - 960 kg/cu. m Germany is extensively dealing with lignite. One German publication mentions following bulk densities : Lignite dry : 500 - 900 kg/cu. m Lignite, wet : 900 kg/cu. m Your first statement regarding bulk density of 1.4 t/cu m for wet lignite looks to be on higher side. The lignite is primarily made from wood.

Lignite, or brown coal, is the lowest-ranked coal, and is placed just above peat in terms of calorific value. It is not a feature of international seaborne coal trades, primarily due to its high water content (which can reach up to 60 per cent) and its lower Btu values (which average 4000–8300 Btu/lb compared with bituminous coals, which ...

 · An important physical change in coal during the lignite rank of coalification is the formation of organized sets of fractures or joints, called cleats. Cleats are what give coal its common blocky appearance. They are also …
