  • Method for increased mine recovery and upgrading of lignite
    Patent number: 4619669
    Abstract: A method is disclosed for upgrading run-of-the-mine (ROM) lignites to remove the gangue (clays, rock etc.) which form ash when the lignite is burned. The unique features of the process, a combination of unit operations in a specified sequence, result in less loss of combustible fuel value without hydrodegradation (the production of a large volume of fines) normally associated with contact of the lignite with water as in pipeline transport of lignite.
