Hydrometallurgical Processing of Manganese Ores: A Review
X-Ray Diffraction analysis showed that the manganese ore was consisted of pyrolusite (MnO 2), rhodonite (MnSiO 3), rhodochrosite (MnCO 3) and hematite (Fe 2 O 3). Manganese ore was also analyzed by thermal analysis to observe their thermal decomposition character. In this study, sulphuric acid (H 2 SO 4, 6 M) was deployed as leaching agent.
