Lignite is a typical low-quality coal. Although the grade of germanium (ranging from 30 ppm to 200 ppm) in lignite is poor, the large reserves of lignite will make it a major raw material for germanium extraction in the future [24,25]. There is an urgent need to develop better technology to utilize the lignite.
