Science definitions for lignite

lignite

[ lĭgnīt′ ]

A soft, brownish-black form of coal having more carbon than peat but less carbon than bituminous coal. Lignite is easy to mine but does not burn as well as other forms of coal. It is a greater polluter than bituminous coal because it has a higher sulphur content. Compare anthracite bituminous coal.
