Scope of Ore Beneficiation: Previously selective mining practices were followed. But after the development of inexpensive ore beneficiation methods, bulk mining practices have proved to be more economical compared to careful selective mining. In a general way the scope of mineral dressing or ore beneficiation is twofold: 1.
