overburden and gangue in mining

In mining, gangue (/ ɡ æ ŋ /) 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; a ......
