In mining gangue /ɡæŋ/ [1] is the oft commercially worthless material that surrounds or is closely mixed with a wanted mineral in an ore deposit It is thus distinct from overburden which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed and from tailings which is rock already stripped of valuable minerals;
