Beneficiation
11.5.3.1 Beneficiation. Mineral beneficiation begins with crushing and grinding of mined ore for near-complete separation of ore and gangue minerals as well as between ore minerals. Each processing step is designed to increase the grade (concentration) of the valuable components of the original ore.
