Abstract The significant fraction of manganese ores available across the globe is ferruginous with high gangue content. About 30% of these types of ores occur as fines (< 1 mm) and are dumped at the mines site, considering it as waste. Different methods have been tried to utilize these ores by 5–15% in the charge mix of submerged arc …

Pure manganese dioxide was successfully produced from low grade pyrolusite ore (β-MnO 2) and sulphur slag.First, the reduction of β-MnO 2, introduced as pure pyrolusite was studied using different ratios of elemental sulphur at different temperature (300–400 °C), in air or in closed stainless tube. The reduction process was …

During the mining, crushing, beneficiation and transportation of rich Mn ores, about 30% of the mined ores are converted into manganese ore fines with low Mn grade (Singh et al., 2011). In India, almost half of manganese ore resources are ferruginous in nature (Singh et al., 2011, Singh and Biswas, 2017).
