The head grade 26.7 Mn % content was used for carrying out the study. Coarse magnetic separation of 0-10mm was not successful. Crushing followed by magnetic separation can enhance Mn content by 8-10 units and can reduce Fe content by 6-8 units. Hence, this process is effective only for ores with Mn >25% & Mn/Fe >1.Web

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.Web
