  • Some Problems in the Crushing and Grinding Stage of

    Selective grinding refers to a kind of grinding phenomenon in which the ore fragmentation degrees is different in the grinding process due to the difference in hardness between minerals. The main purpose of the crushing and grinding operation is not to reduce the ore particle size but to dissociate the useful minerals from the gangue minerals.
