examples of iron ores and the gangue

Gangue

2018 10 26&ensp·&enspIn mining, gangue / ɡ æ ŋ / ismercially 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.
