Extraction of manganese from iron rich MnO2 ores via ...
In this study, selective sulfation roasting–water leaching is proposed for recovering manganese from iron rich low-grade manganese oxide ores using SO 2 as reductant. Thermodynamic analysis indicated that manganese dioxide is readily transformed to sulfate. However, the sulfation of ferric oxide only occurs in the presence of both SO 2 and O 2.

2015-7-1 · The extraction of manganese/iron as a function of SO 2 partial pressure, as given by (SO 2 / (SO 2 + N 2)), is shown in Fig. 6. Sulfation roasting was proceeded at 500 °C for 60 min with average ore particle size of 104 μm. It reveals that manganese extraction increases from 55.3% to 90.2% as SO 2 partial pressure increases from 0.1% to 0.5% ...
