Lignite, generally yellow to dark brown or rarely black coal that formed from peat at shallow depths and temperatures lower than 100 °C (212 °F). It is the first product of coalification and is intermediate between peat and subbituminous coal according to the coal classification used in the United

17.6.1.1 Use of Lignite. Lignite is a brown, fibrous, low-grade coal with a relatively low carbon and high moisture content. This acts as a potential cation exchanger and may be used efficiently to remove and recover metal ions from AMD, as shown experimentally by Mohan and Chander (2006). Lignite has been characterized and used for AMD treatment.

Lignite is a dark brown to black combustible mineral formed over millions of years by the partial decomposition of plant material subject to increased pressure and temperature in an airless atmosphere. In simple terms, lignite is coal. Lignite is abundant and accessible. Lignite-generated electricity is reliable. Lignite-generated electricity is environmentally compatible.

The primary objective of the Lignite Energy Council is to maintain a viable lignite coal industry and enhance development of the region's lignite coal resources for use in generating electricity, synthetic natural gas and valuable byproducts. Members of the Lignite Energy Council include mining companies, major users that use lignite to generate electricity, synthetic natural gas and other ...
