In this study, three types of low-grade iron ores with different grain sizes were crushed to −3 mm by a …

Ore vs. Gangue — What's the Difference?

In mining, gangue is the 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 …
