Lost Town of Lignite - Blue Ridge Outdoors Magazine
Lignite: the name alone speaks to decay. Lignite is the shabbiest, lowest-quality coal, the product of millions of years of decay. Named for the stuff its residents hauled out of the ground in the late 1800s, the town of Lignite was once host to homes, a company store, …

Elemental characterization of lignite from Afşin-Elbistan ...
A mass down to 100 g was used for grinding in the IKA-mill down to mm scale. Approximately 25 g of each lignite material was provided to the Nuclear Physics Institute ASCR in Řež, Czech Republic. Here, the samples were milled again in an agate planetary ball mill to ensure finer particles of the lignite powder and consequent homogeneity.

Lignite - an overview | ScienceDirect Topics
This type of mill is often used in lignite-fired power stations where hot combustion gases are extracted from the furnace and used to dry the wet fuel while milling it at the same time as making the atmosphere inert. The mill is also acting as a fan sucking the gas from the furnace and blowing it to the burners.

Geology of North Dakota - Wikipedia
In 1955, ore grade uranium was found in lignite between Belfield and Amidon in southeast Billings County. Uranium dissolved from enriched ash and percolated upward into the coal. Only a few hundred tons were ever extracted and ended in 1967 due to difficulty milling lignite compared with sandstone deposits in the Colorado Plateau.
