Ferro-manganese by aluminothermic method upto 10 kg ore scale. Some salient datas are given in this paper. For production of ferro-manganese by aluminothermic method, the ore should have more than 46% Mn. The Mn/Fe ratio desired is 9. However, 6 and above is acceptable. Sulphur and phosphorus are deleterious impurities in the ore. Phosphorus

Rudramuniyappa et al. [3] reported that reduction roasting followed by magnetic separation is considered to be the best method for upgrading the Chikkanayakanahalli manganese ores. They also showed that tabling studies carried out were not encouraging, probably due to the similar behavior of Mn and Fe. Rao et al.

Abstract：The reduction of manganese dioxide in low-grade manganese ore by biomass roasting process was investigated for extracting manganese from poor manganese ore more effectively. In this study,the cinder of ore fines and sawdust was further leached by sulphuric acid to obtain MnSO4. Over 97% manganese in ores can be converted into MnSO4. Effects of the mass ratio of manganese ore …

Manganese oxide ore is mainly used by gravity separation method, which mainly adopts ore washing-gravity separation process or ore washing-reduction roasting magnetic separation-gravity separation process. Of course, for refractory manganese ore often need to combine two or even more than a variety of separation methods.

There are many chemical beneficiations for manganese, and the more promising ones are the dithionate method, the black manganese ore method and the bacterial immersion. In actual production, most of the manganese carbonate ore beneficiation methods are strong magnetic separation, heavy medium ore dressing and flotation separation.
