Manganese ore fines and concentrates (size: −5 mm) can provide sufficient raw material to produce high-quality manganese alloys. Sintering is considered as the most efficient agglomeration method [8, 18]. Mn content could be upgraded by 5–15 wt% after the beneficiation process, particularly for rhodochrosite and pyrolusite, which have ...

Generation of fines considerably depends on the nature of the ore, mining operations and handling systems. Particularly in Ukwa and Balaghat mines, the nature of ore is friable and generation of fines is considerable and is to the tune of 14% and 12% respectively. The percentage of manganese varies from 30-35% in the fines.
