Gangue minerals SpringerLink

Ore, as mined, contains ore minerals, gangue minerals, and country rock. A mass of mineral matter is not considered ore unless one or more of its ore minerals can be recovered on a profitable basis. As originally used, ore minerals were metal bearing (see Metallic Minerals).More recently, nonmetallic minerals of commercial importance are considered ore minerals (see Mineral Industries).
