12.10.2018 · The separation efficiency depends on both the content of poor-crystalline iron oxide in the raw ore and the leaching conditions. In the first stage, the reactant diffusion was the rate-limiting step for the dissolution of both manganese and poor-crystalline iron oxide with activation energy of 10.48 kJ/mol and 20.18 kJ/mol, respectively.
Extraction and separation of manganese and iron …
In the oxide type manganese ore, the manganese is often present in the insoluble form of Mn 4+ and iron often exists in the state of Fe 3+. In order to obtain soluble Mn 2+ , Mn 4+ must be converted into Mn 2+ , therefore, reductants are applied to reduce Mn 4+ into Mn 2+ during the acid leaching process (Named as direct reduction leaching).
