However, the complexity of new ore bodies requires fine grinding to liberate valuable minerals, which produces particles with sizes too fine for an efficient mineral flotation and separation. In addition, fine grinding has produced undesirable effects, where gangue minerals too often dilute the valuable mineral concentrates.
