This thesis has to do with the selective flotation of the manganese oxide minerals in an ore from Charco Redondo Mine, Oriente Province, Cuba. Since a sound knowledge of the nature of the emulsion-induced flotation process of these minerals does not exist, experimental research constitutes the most valuable resource for determining the extent to which different reagents …

This study describes the degradation of thiocyanate by manganese oxides. With NaOH and CaO as precipitating agents, two manganese oxides, i.e. MnO x /Na and MnO x /Ca, were prepared using MnSO 4 ·H 2 O as Mn resource and air as oxidant. The influence of various reaction parameters like pH, manganese oxide dosage and initial thiocyanate concentration …

The isoelectric point (IEP) of manganese oxide is measured on samples prepared by heating β-MnO2 and amorphous manganese oxide, MnO1.75, at temperatures from 200 to 1400°C. The IEP values thus obtained are characteristic of each stage of the oxidation of manganese oxide; that is, <5.1 for MnO2, 7.6–9.0 for α-Mn2O3, and 3.3–5.2 for Mn3O4. These values can be …

Therefore, flotation is only used for a part of the fine-grained rhodochrosite and manganese oxide slimes. The flotation of manganese ore can use positive flotation and reverse flotation. At present, anion-positive flotation is widely used, and cation reverse flotation is still in the experimental stage.
